CS Chip select Disables or enables device operation by masking or enabling all inputs except CLK, CKE and DQM CKE Clock enable Masks system clock to freeze operation from the next clock cycle. CKE should be enabled at least one cycle prior to new command. Disable input buffers for power down in standby. CKE should be enabled 1CLK+tSS prior to valid command. A0 ~ A12 Address Row/column addresses are multiplexed on the same pins. Row address : RA0 ~ RA12 Column address : (x16 : CA0 ~ CA9) BA0 ~ BA1 Bank select address Selects bank to be activated during row address latch time. Selects bank for read/write during column address latch time. RAS Row address strobe Latches row addresses on the positive going edge of the CLK with RAS low. Enables row access & precharge. CAS Column address strobe Latches column addresses on the positive going edge of the CLK with CAS low. Enables column access. WE Write enable Enables write operation and row precharge. Latches data in starting from CAS, WE active. DQM0 ~ 7 Data input/output mask Makes data output Hi-Z, tSHZ after the clock and masks the output. Blocks data input when DQM active. (Byte masking) DQ0 ~ 63 Data input/output Data inputs/outputs are multiplexed on the same pins. VDD/VSS Power supply/ground Power and ground for the input buffers and the core logic.

Auto refresh functions are as 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. 4. BA0 ~ BA1 : Bank select addresses. If both BA0 and BA1 are "Low" at read, write, row active and precharge, bank A is selected. If BA0 is "High" and BA1 is "Low" at read, write, row active and precharge, bank B is selected. If BA0 is "Low" and BA1 is "High" at read, write, row active and precharge, bank C is selected. If both BA0 and BA1 are "High" at read, write, row active and precharge, bank D is selected. If A10/AP is "High" at row precharge, BA0 and BA1 is ignored and all banks are selected. 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.
