NOTES: 1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time and then rounding off to the next higher integer. 2. Minimum delay is required to complete write.
3. Maximum burst refresh cycle : 8
4. All parts allow every cycle column address change. 5. In case of row precharge interrupt, auto precharge and read burst stop.

(V=Valid, X=Dont Care, H=Logic High, L=Logic Low) NOTES : 1. OP Code : Operand Code A0 ~ A11 & BA0 ~ BA1 : Program keys. (@MRS) 2. MRS can be issued only at all banks precharge state. A new command can be issued after 2 CLK cycles of MRS. 3. Auto refresh functions are the same as CBR refresh of DRAM. The automatical precharge without row precharge command is meant by "Auto". Auto/self refresh can be issued only at all banks precharge state. Partial self refresh can be issued only after setting partial self refresh mode of EMRS. 4. BA0 ~ BA1 : Bank select addresses. 5. During burst read or write with auto precharge, new read/write command can not be issued. Another bank read/write command can be issued after the end of burst. New row active of the associated bank can be issued at tRP after the end of burst. 6. Burst stop command is valid at every burst length. 7. DQM sampled at the positive going edge of CLK masks the data-in at that same CLK in write operation (Write DQM latency is 0), but in read operation, it makes the data-out Hi-Z state after 2 CLK cycles. (Read DQM latency is 2).

Temperature Compensated Self Refresh
1. In order to save power consumption, Mobile-DRAM includes the internal temperature sonsor and control units to control the self refresh cycle automatically according to the two temperature range : 45 C and 85 C(for Extended), 70 C(for Commercial). 2. If the EMRS for external TCSR is issued by the controller, this EMRS code for TCSR is ignored. 3. It has +/-5 C tolerance.

B. POWER UP SEQUENCE
1. Apply power and attempt to maintain CKE at a high state and all other inputs may be undefined. - Apply VDD before or at the same time as VDDQ. 2. Maintain stable power, stable clock and NOP input condition for a minimum of 200us. 3. Issue precharge commands for all banks of the devices. 4. Issue 2 or more auto-refresh commands. 5. Issue a mode register set command to initialize the mode register. 6. Issue a extended mode register set command to define DS or PASR operating type of the device after normal MRS. For operating with DS or PASR, set DS or PASR mode in EMRS setting stage. In order to adjust another mode in the state of DS or PASR mode, additional EMRS set is required but power up sequence is not needed again at this time. In that case, all banks have to be in idle state prior to adjusting EMRS set.
