2. MRS can be issued only at both banks precharge state.
3. Auto refresh functions as same as CBR refresh of DRAM.
4. BA : Bank select address.
5. During burst read or write with auto precharge, new read write command cannot be issued.
6. Burst 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),
A0~A10/AP,BA : Program keys. (@MRS)
A new command can be issued after 2 clock cycle of MRS.
The automatical precharge without Row precharge command is meant by “Auto”.
Auto/Self refresh can be issued only at both precharge state.
If “Low” at read, write, Row active and precharge, bank A is selected.
If “High” at read, write, Row active and precharge, bank B is selected.
If A10/AP is “High” at Row precharge, BA is ignored and both banks are selected.
Another bank read write command can be issued at every burst length.
but makes the data-out Hi-Z state after 2 CLK cycles. (Read DQM latency is 2)
