OP Code: Operand Code A0~A10, BA: Program keys. (@MRS, EMRS) 2. MRS can be issued only when all banks are at precharge state. A new command can be issued after 2 clock cycle of MRS, EMRS. 3. Auto refresh functions is same as CBR refresh of DRAM. The automatical precharge without Row precharge command is meant by “Auto”. Auto/Self refresh can be issued only when all banks are at precharge state. 4. BA: Bank select address. 5. During burst read or write with auto precharge, new read/write command cannot be issued. Another bank read/write command can be issued at every burst length. 6. Bust stop command is valid at every burst length. 7. DQM sampled at positive going edge of a CLK masks the data-in at the very CLK (Write DQM latency is 0) but masks the data-out Hi-Z state after 2 CLK cycles. (Read DQM latency is 2) 8. After Deep Power Down mode exit, a full new initialization of the memory device is mandatory. |
