Disables or enables device operation by masking or enabling all inputs except CLK, CKE and DQM 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. Row/column addresses are multiplexed on the same pins. Row address : RA0 ~ RA11, Column address : (x4 : CA0 ~ CA9, x8 : CA0 ~ CA8 , x16 : CA0 ~ CA7) Selects bank to be activated during row address latch time. Selects bank for read/write during column address latch time. La.
