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). 9 December 2003 K4M64163PH - R(B)G/F Mobile-SDRAM A.

In order to save power consumption, Mobile SDRAM has PASR option. 2. Mobile SDRAM supports 3 kinds of PASR in self refresh mode : Full Array, 1/2 of Full Array and 1/4 of Full Array.

In order to save power consumption, Mobile-SDRAM includes the internal temperature sensor and control units to control the self refresh cycle automatically according to the two temperature range ; Max. 40 °C, Max. 85 °C. 2. If the EMRS for external TCSR is issued by the controller, this EMRS code for TCSR is ignored.

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. EMRS cycle is not mandatory and the EMRS command needs to be issued only when DS or PASR is used. The default state without EMRS command issued is the half driver strength and full array refreshed. The device is now ready for the operation selected by EMRS. 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. 11 December 2003 K4M64163PH - R(B)G/F Mobile-SDRAM C. BURST SEQUENCE 1.
