Description
The EDD5104AD, the EDD5108AD and the EDD5116AD are 512M bits Double Data Rate (DDR) SDRAM. Read and write operations are performed at the cross points of the CK and the /CK. This highspeed data transfer is realized by the 2 bits prefetchpipelined architecture. Data strobe (DQS) both for read and write are available for high speed and reliable data bus design. By setting extended mode register, the on-chip Delay Locked Loop (DLL) can be set enable or disable. It is packaged in standard 66-pin plastic TSOP (II).

Notes: 1. On all AC measurements, we assume the test conditions shown in the next page. For timing parameter definitions, see `Timing Waveforms' section. 2. This parameter defines the signal transition delay from the cross point of CK and /CK. The signal transition is defined to occur when the signal level crossing VTT. 3. The timing reference level is VTT. 4. Output valid window is defined to be the period between two successive transition of data out or DQS (read) signals. The signal transition is defined to occur when the signal level crossing VTT. 5. tHZ is defined as DOUT transition delay from Low-Z to High-Z at the end of read burst operation. The timing reference is cross point of CK and /CK. This parameter is not referred to a specific DOUT voltage level, but specify when the device output stops driving. 6. tLZ is defined as DOUT transition delay from High-Z to Low-Z at the beginning of read operation. This parameter is not referred to a specific DOUT voltage level, but specify when the device output begins driving. 7. Input valid windows is defined to be the period between two successive transition of data input or DQS (write) signals. The signal transition is defined to occur when the signal level crossing VREF. 8. The timing reference level is VREF. 9. The transition from Low-Z to High-Z is defined to occur when the device output stops driving. A specific reference voltage to judge this transition is not given. 10. tCK (max.) is determined by the lock range of the DLL. Beyond this lock range, the DLL operation is not assured. 11. tCK = tCK (min.) when these parameters are measured. Otherwise, absolute minimum values of these values are 10% of tCK. 12. VDD is assumed to be 2.5V 0.2V. VDD power supply variation per cycle expected to be less than 0.4V/400 cycle. 13. tDAL = (tWR/tCK)+(tRP/tCK) For each of the terms above, if not already an integer, round to the next highest integer. Example: For -7A Speed at CL = 2.5, tCK = 7.5ns, tWR = 15ns and tRP= 20ns, tDAL = (15ns/7.5ns) + (20ns/7.5ns) = (2) + (3) tDAL = 5 clocks

Pin Function
CK, /CK (input pins) The CK and the /CK are the master clock inputs. All inputs except DM, DQS and DQs are referred to the cross point of the CK rising edge and the /CK falling edge. When a read operation, DQS and DQs are referred to the cross point of the CK and the /CK. When a write operation, DQS and DQs are referred to the cross point of the DQS and the VREF level. DQS for write operation is referred to the cross point of the CK and the /CK. CK is the master clock input to this pin. The other input signals are referred at CK rising edge. /CS (input pin) When /CS is Low, commands and data can be input. When /CS is High, all inputs are ignored. However, internal operations (bank active, burst operations, etc.) are held. /RAS, /CAS, and /WE (input pins) These pins define operating commands (read, write, etc.) depending on the combinations of their voltage levels. See "Command operation". A0 to A12 (input pins) Row address (AX0 to AX12) is determined by the A0 to the A12 level at the cross point of the CK rising edge and the /CK falling edge in a bank active command cycle. Column address (See "Address Pins Table") is loaded via the A0 to the A9, A11 and A12 at the cross point of the CK rising edge and the /CK falling edge in a read or a write command cycle. This column address becomes the starting address of a burst operation. [Address Pins Table]
Address (A0 to A12) Part number EDD5104AD EDD5108AD EDD5116AD Row address AX0 to AX12 AX0 to AX12 AX0 to AX12 Column address AY0 to AY9, AY11, AY12 AY0 to AY9, AY11 AY0 to AY9
A10 (AP) (input pin) A10 defines the precharge mode when a precharge command, a read command or a write command is issued. If A10 = High when a precharge command is issued, all banks are precharged. If A10 = Low when a precharge command is issued, only the bank that is selected by BA1/BA0 is precharged. If A10 = High when read or write command, auto-precharge function is enabled. While A10 = Low, auto-precharge function is disabled. BA0 and BA1 (input pins) BA0, BA1 are bank select signals (BA). The memory array is divided into bank 0, bank 1, bank 2 and bank 3. (See Bank Select Signal Table) [Bank Select Signal Table]

CKE (input pin) This pin determines whether or not the next CK is valid. If CKE is High, the next CK rising edge is valid. If CKE is Low. CKE controls power down and self-refresh. The power down and the self-refresh commands are entered when the CKE is driven Low and exited when it resumes to High. CKE must be maintained high throughout read or write access. The CKE level must be kept for 1 CK cycle at least, that is, if CKE changes at the cross point of the CK rising edge and the /CK falling edge with proper setup time tIS, by the next CK rising edge CKE level must be kept with proper hold time tIH. DM, LDM and UDM (input pins) DMs are the reference signal of the data input mask function. DMs are sampled at the cross point of DQS and VREF. DMs provide the byte mask function. When DM = High, the data input at the same timing are masked while the internal burst counter will be count up. In x16 products, LDM controls the lower byte (DQ0 to DQ7) and UDM controls the upper byte (DQ8 to DQ15) of write data. DQ0 to DQ15 (input/output pins) Data is input to and output from these pins (DQ0 to DQ3; EDD5104AD, DQ0 to DQ7; EDD5108AD, DQ0 to DQ15; EDD5116AD). DQS, LDQS and UDQS (input and output pins) DQS provides the read data strobes (as output) and the write data strobes (as input). In x16 products, LDQS is the lower byte (DQ0 to DQ7) data strobe signal, UDQS is the upper byte (DQ8 to DQ15) data strobe signal. VDD, VSS, VDDQ, VSSQ (Power supply) VDD and VSS are power supply pins for internal circuits. VDDQ and VSSQ are power supply pins for the output buffers.

Auto-refresh command [REF] This command executes auto-refresh. The banks and the ROW addresses to be refreshed are internally determined by the internal refresh controller. The average refresh cycle is 7.8 s. The output buffer becomes High-Z after autorefresh start. Precharge has been completed automatically after the auto-refresh. The ACT or MRS command can be issued tRFC after the last auto-refresh command. Self-refresh entry [SELF] This command starts self-refresh. The self-refresh operation continues as long as CKE is held Low. During the selfrefresh operation, all ROW addresses are repeated refreshing by the internal refresh controller. A self-refresh is terminated by a self-refresh exit command. Power down mode entry [PDEN] tPDEN (= 1 cycle) after the cycle when [PDEN] is issued. The DDR SDRAM enters into power-down mode. In power down mode, power consumption is suppressed by deactivating the input initial circuit. Power down mode continues while CKE is held Low. No internal refresh operation occurs during the power down mode. [PDEN] do not disable DLL. Self-refresh exit [SELFX] This command is executed to exit from self-refresh mode. To issue non-read commands, tSNR has to be satisfied. ((tSNR =)10 cycles for tCK = 7.5 ns or 12 cycles for tCK = 6.0 ns after [SELFX]) To issue read command, tSRD has to be satisfied to adjust DOUT timing by DLL. (200 cycles after [SELFX]) After the exit, input auto-refresh command within 7.8 s. Power down exit [PDEX] The DDR SDRAM can exit from power down mode tPDEX (1 cycle min.) after the cycle when [PDEX] is issued.

Operation of the DDR SDRAM
Power-up Sequence (1) Apply power and maintain CKE at an LVCMOS low state (all other inputs are undefined). Apply VDD before or at the same time as VDDQ. Apply VDDQ before or at the same time as VTT and VREF. (2) Start clock and maintain stable condition for a minimum of 200 s. (3) After the minimum 200 s of stable power and clock (CK, /CK), apply NOP and take CKE high. (4) Issue precharge all command for the device. (5) Issue EMRS to enable DLL. (6) Issue a mode register set command (MRS) for "DLL reset" with bit A8 set to high (An additional 200 cycles of clock input is required to lock the DLL after every DLL reset). (7) Issue precharge all command for the device. (8) Issue 2 or more auto-refresh commands. (9) Issue a mode register set command to initialize device operation with bit A8 set to low in order to avoid resetting the DLL.

Power-up Sequence after CKE Goes High Mode Register and Extended Mode Register Set There are two mode registers, the mode register and the extended mode register so as to define the operating mode. Parameters are set to both through the A0 to the A12 and BA0, BA1 pins by the mode register set command [MRS] or the extended mode register set command [EMRS]. The mode register and the extended mode register are set by inputting signal via the A0 to the A12 and BA0, BA1 during mode register set cycles. BA0 and BA1 determine which one of the mode register or the extended mode register are set. Prior to a read or a write operation, the mode register must be set. Remind that no other parameters shown in the table bellow are allowed to input to the registers.

Read/Write Operations
Bank active A read or a write operation begins with the bank active command [ACT]. The bank active command determines a bank address and a row address. For the bank and the row, a read or a write command can be issued tRCD after the ACT is issued.
Read operation The burst length (BL), the /CAS latency (CL) and the burst type (BT) of the mode register are referred when a read command is issued. The burst length (BL) determines the length of a sequential output data by the read command that can be set to 2, 4, or 8. The starting address of the burst read is defined by the column address, the bank select address which are loaded via the A0 to A12 and BA0, BA1 pins in the cycle when the read command is issued. The data output timing are characterized by CL and tAC. The read burst start CL * tCK + tAC (ns) after the clock rising edge where the read command are latched. The DDR SDRAM output the data strobe through DQS simultaneously with data. tRPRE prior to the first rising edge of the data strobe, the DQS are driven Low from VTT level. This low period of DQS is referred as read preamble. The burst data are output coincidentally at both the rising and falling edge of the data strobe. The DQ pins become High-Z in the next cycle after the burst read operation completed. tRPST from the last falling edge of the data strobe, the DQS pins become High-Z. This low period of DQS is referred as read postamble.

Read Operation (/CAS Latency)
Write operation The burst length (BL) and the burst type (BT) of the mode register are referred when a write command is issued. The burst length (BL) determines the length of a sequential data input by the write command that can be set to 2, 4, or 8. The latency from write command to data input is fixed to 1. The starting address of the burst read is defined by the column address, the bank select address which are loaded via the A0 to A12, BA0 to BA1 pins in the cycle when the write command is issued. DQS should be input as the strobe for the input-data and DM as well during burst operation. tWPRE prior to the first rising edge of the DQS should be set to Low and tWPST after the last falling edge of the data strobe can be set to High-Z. The leading low period of DQS is referred as write preamble. The last low period of DQS is referred as write postamble.

Auto Precharge Read with auto-precharge The precharge is automatically performed after completing a read operation. The precharge starts tRPD (BL/2) cycle after READA command input. tRAP specification for READA allows a read command with auto precharge to be issued to a bank that has been activated (opened) but has not yet satisfied the tRAS (min) specification. A column command to the other active bank can be issued the next cycle after the last data output. Read with auto-precharge command does not limit row commands execution for other bank.

NOTES FOR CMOS DEVICES
1 PRECAUTION AGAINST ESD FOR MOS DEVICES
Exposing the MOS devices to a strong electric field can cause destruction of the gate oxide and ultimately degrade the MOS devices operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it, when once it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. MOS devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. MOS devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor MOS devices on it.
2 HANDLING OF UNUSED INPUT PINS FOR CMOS DEVICES
No connection for CMOS devices input pins can be a cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. The unused pins must be handled in accordance with the related specifications.
3 STATUS BEFORE INITIALIZATION OF MOS DEVICES
Power-on does not necessarily define initial status of MOS devices. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the MOS devices with reset function have not yet been initialized. Hence, power-on does not guarantee output pin levels, I/O settings or contents of registers. MOS devices are not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for MOS devices having reset function.
