NOTES: (1) (2) (3) (4) (5) (6) (7) (8) (9) (10) All voltages referenced to VSS, VSSQ. VREF is expected to track variations in VDDQ DC level of the transmitting device. Peak to peak AC noise on VREF may not exceed 2% VREF (DC). Overshoot limit: VIH (max) = VDDQ + 0.7 V with a pulse width 5 ns. Undershoot limit: VIL (min) = -0.7 V with a pulse width 5 ns. VIH (DC) and VIL (DC) are levels to maintain the current logic state. VIH (AC) and VIL (AC) are levels to change to the new logic state. VID is differential voltage of CLK input level and CLK input level. The value of VX (AC) is expected to equal VDDQ/2 of the transmitting device. VISO means {VICK (CLK) + VICK ( CLK )} /2 Refer to the figure below.

NOTES: (1) Transition times are measured between VIH min (DC) and VIL max (DC). Transition (rise and fall) of input signals have a fixed slope. (2) If the result of nominal calculation with regard to tCK contains more than one decimal place, the result is rounded up to the nearest decimal place. (i.e., tDQSS = 0.8 x tCK, tCK = 3.3 ns, 0.8 x 3.3 ns = 2.64 ns is rounded up to 2.7 ns.) These parameters are measured from the differential clock (CLK and CLK ) AC cross point. These parameters are measured from signal transition point of DS crossing VREF level. The tREFI (max) applies to equally distributed refresh method. The tREFI (min) applies to both burst refresh method and distributed refresh method. In such case, the average interval of eight consecutive Auto-Refresh commands has to be more than 400 ns always. In other words, the number of Auto-Refresh cycles which can be performed within 3.2 s (8 x 400 ns) is to 8 times in the maximum. Low Impedance State is specified at VDDQ/2 0.1 V from steady state. High Impedance State is specified where output buffer is no longer driven. These parameters depend on the clock jitter. These parameters are measured at stable clock. Output timing is measured by using Normal driver strength at VDDQ = 1.7 V 1.9 V. Output timing is measured by using Strong driver strength at VDDQ = 1.4 V 1.6 V. These parameters are measured at tCK = minimum 6.0ns. When tCK is longer than 6.0ns, these parameters are specified as below for all speed version. tCKQS (MIN/MAX) = -0.6ns / 0.6ns, tAC (MIN/MAX) = -0.65ns / 0.65ns

POWER UP SEQUENCE
(1) (2) (3) (4) (5) (6) (7) (8) (9) As for PD , being maintained by the low state ( 0.2 V) is desirable before a power-supply injection. Apply VDD before or at the same time as VDDQ. Apply VDDQ before or at the same time as VREF. Start clock (CLK, CLK ) and maintain stable condition for 200 s (min). After stable power and clock, apply DESL and take PD =H. Issue EMRS to enable DLL and to define driver strength and data strobe type. (Note: 1) Issue MRS for set CAS latency (CL), Burst Type (BT), and Burst Length (BL). (Note: 1) Issue two or more Auto-Refresh commands (Note: 1). Ready for normal operation after 200 clocks from Extended Mode Register programming.
NOTES: (1) Sequence 6, 7 and 8 can be issued in random order. (2) (3) L = Logic Low, H = Logic High DQ output is Hi-Z state during power upsequence.

FUNCTIONAL DESCRIPTION Network FCRAM
TM
The FCRAMTM is an acronym of Fast Cycle Random Access Memory. The Network FCRAMTM is competent to perform fast random core access, low latency and high-speed data transfer.
PIN FUNCTIONS
CLOCK INPUTS: CLK & CLK
The CLK and CLK inputs are used as the reference for synchronous operation. CLK is master clock input. The CS , FN and all address input signals are sampled on the crossing of the positive edge of CLK and the negative edge of CLK . The QS and DQ output data are aligned to the crossing point of CLK and CLK . The timing reference point for the differential clock is when the CLK and CLK signals cross during a transition.
POWER DOWN: PD
The PD input controls the entry to the Power Down or Self-Refresh modes. The PD input does not have a Clock Suspend function like a CKE input of a standard SDRAMs, therefore it is illegal to bring PD pin into low state if any Read or Write operation is being performed.
CHIP SELECT & FUNCTION CONTROL: CS & FN
The CS and FN inputs are a control signal for forming the operation commands on FCRAMTM. Each operation mode is decided by the combination of the two consecutive operation commands using the CS and FN inputs.
BANK ADDRESSES: BA0 & BA1
The BA0 and BA1 inputs are latched at the time of assertion of the RDA or WRA command and are selected the bank to be used for the operation. BA0 and BA1 also define which mode register is loaded during the Mode Register Set command (MRS or EMRS).
BA0 Bank #0 Bank #1 Bank #2 Bank #3 0 1 0 1 BA1 0 0 1 1
ADDRESS INPUTS: A0~A14
Address inputs are used to access the arbitrary address of the memory cell array within each bank. The Upper Addresses with Bank addresses are latched at the RDA or WRA command and the Lower Addresses are latched at the LAL command. The A0 to A14 inputs are also used for setting the data in the Regular or Extended Mode Register set cycle.
I/O Organization 18 bits UPPER ADDRESS A0~A14 LOWER ADDRESS A0~A6
Rev 1.4 2005-10-19 49/57
TC59LM818DMB-33,-40
DATA INPUT/OUTPUT: DQ0~DQ17
The input data of DQ0 to DQ17 are taken in synchronizing with the both edges of DS input signal. The output data of DQ0 to DQ17 are outputted synchronizing with the both edges of QS output signal.
DATA STROBE: DS, QS
Method of data strobe is chosen by Extended mode register. (1) Unidirectional DS / QS mode DS is input signal and QS is output signal. Both edges of DS are used to sample all DQs at Write operation. Both edges of QS are used for trigger signal of all DQs at Read operation. During Write, Auto-Refresh and NOP cycle, QS assert always "Low" level. QS is Hi-Z in Self-Refresh mode. (2) Unidirectional DS / Free running QS mode DS is input signal and QS is output signal. Both edge of DS are used to sample all DQs at Write operation. Both edges of QS are used for trigger signal of all DQs at Read operation. QS assert always toggle signal except Self-Refresh mode. This strobe type is easy to use for pin to pin connect application.
POWER SUPPLY: VDD, VDDQ, VSS, VSSQ

COMMAND FUNCTIONS and OPERATIONS
TC59LM818DMB are introduced the two consecutive command input method. Therefore, except for Power Down mode, each operation mode decided by the combination of the first command and the second command from stand-by states of the bank to be accessed.
Read Operation (1st command + 2nd command = RDA + LAL)
Issuing the RDA command with Bank Addresses and Upper Addresses to the idle bank puts the bank designated by Bank Address in a read mode. When the LAL command with Lower Addresses is issued at the next clock of the RDA command, the data is read out sequentially synchronizing with the both edges of QS output signal (Burst Read Operation). The initial valid read data appears after CAS latency from the issuing of the LAL command. The valid data is outputted for a burst length. The CAS latency, the burst length of read data and the burst type must be set in the Mode Register beforehand. The read operated bank goes back automatically to the idle state after lRC.
Write Operation (1st command + 2nd command = WRA + LAL)
Issuing the WRA command with Bank Addresses and Upper Addresses to the idle bank puts the bank designated by Bank Address in a write mode. When the LAL command with Lower Addresses is issued at the next clock of the WRA command, the input data is latched sequentially synchronizing with the both edges of DS input signal (Burst Write Operation). The data and DS inputs have to be asserted in keeping with clock input after CAS latency-1 from the issuing of the LAL command. The DS has to be provided for a burst length. The CAS latency and the burst type must be set in the Mode Register beforehand. The write operated bank goes back automatically to the idle state after lRC. Write Burst Length is controlled by VW0 and VW1 inputs with LAL command. See VW truth table.
Auto-Refresh Operation (1st command + 2nd command = WRA + REF)
TC59LM818DMB are required to refresh like a standard SDRAM. The Auto-Refresh operation is begun with the REF command following to the WRA command. The Auto-Refresh mode can be effective only when all banks are in the idle state. In a point to notice, the write mode started with the WRA command is canceled by the REF command having gone into the next clock of the WRA command instead of the LAL command. The minimum period between the Auto-Refresh command and the next command is specified by lREFC. However, about a synthetic average interval of Auto-Refresh command, it must be careful. In case of equally distributed refresh, Auto-Refresh command has to be issued within once for every 3.9 s by the maximum. In case of burst refresh or random distributed refresh, the average interval of eight consecutive Auto-Refresh commands has to be more than 400 ns always. In other words, the number of Auto-Refresh cycles that can be performed within 3.2 s (8 x 400 ns) is to 8 times in the maximum.
Self-Refresh Operation (1st command + 2nd command = WRA + REF with PD = "L")
In case of Self-Refresh operation, refresh operation can be performed automatically by using an internal timer. When all banks are in the idle state and all outputs are in Hi-Z states, the TC59LM818DMB become Self-Refresh mode by issuing the Self-Refresh command. PD has to be brought to "Low" within tFPDL from the REF command following to the WRA command for a Self-Refresh mode entry. In order to satisfy the refresh period, the Self-Refresh entry command should be asserted within 3.9 s after the latest Auto-Refresh command. Once the device enters Self-Refresh mode, the DESL command must be continued for lREFC period. In addition, it is desirable that clock input is kept in lCKD period. The device is in Self-Refresh mode as long as PD held "Low". During Self-Refresh mode, all input and output buffers are disabled except for PD , therefore the power dissipation lowers. Regarding a Self-Refresh mode exit, PD has to be changed over from "Low" to "High" along with the DESL command, and the DESL command has to be continuously issued in the number of clocks specified by lREFC. The Self-Refresh exit function is asynchronous operation. It is required that one Auto-Refresh command is issued to avoid the violation of the refresh period just after lREFC from Self-Refresh exit.
Power Down Mode ( PD = "L")
When all banks are in the idle state and DQ outputs are in Hi-Z states, the TC59LM818DMB become Power Down Mode by asserting PD is "Low". When the device enters the Power Down Mode, all input and output buffers are disabled after specified time except for PD , CLK, CLK and QS. Therefore, the power dissipation lowers. To exit the Power Down Mode, PD has to be brought to "High" and the DESL command has to be issued for lPDA cycle after PD goes high. The Power Down exit function is asynchronous operation.

Mode Register Set (1st command + 2nd command = RDA + MRS)
When all banks are in the idle state, issuing the MRS command following to the RDA command can program the Mode Register. In a point to notice, the read mode started with the RDA command is canceled by the MRS command having gone into the next clock of the RDA command instead of the LAL command. The data to be set in the Mode Register is transferred using A0 to A14, BA0 and BA1 address inputs. The TC59LM818DMB have two mode registers. These are Regular and Extended Mode Register. The Regular or Extended Mode Register is chosen by BA0 and BA1 in the MRS command. The Regular Mode Register designates the operation mode for a read or write cycle. The Regular Mode Register has four function fields. The four fields are as follows: (R-1) Burst Length field to set the length of burst data (R-2) Burst Type field to designate the lower address access sequence in a burst cycle (R-3) CAS Latency field to set the access time in clock cycle (R-4) Test Mode field to use for supplier only. The Extended Mode Register has three function fields. The three fields are as follows: (E-1) DLL Switch field to choose either DLL enable or DLL disable (E-2) Output Driver Impedance Control field. (E-3) Data Strobe Select Once those fields in the Mode Register are set up, the register contents are maintained until the Mode Register is set up again by another MRS command or power supply is lost. The initial value of the Regular or Extended Mode Register after power-up is undefined, therefore the Mode Register Set command must be issued before proper operation. * Regular Mode Register/Extended Mode Register change bits (BA0, BA1) These bits are used to choose either Regular MRS or Extended MRS
