Note :
1. OP Code: Operand Code
A0~A11, BS0, BS1: Program keys. (@MRS)
2. MRS can be issued only at both banks precharge state.
A new command can be issued after 2 clock cycle of MRS.
3. Auto refresh functions 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 both precharge state.
4. BS0, BS1 : Bank select address.
If both BS1 and BS0 are “Low” at read, write, row active and precharge, bank A is selected.
If both BS1 is “Low” and BS0 is “High” at read, write, row active and precharge, bank B is selected.
If both BS1 is “High” and BS0 is “Low” at read, write, row active and precharge, bank C is selected.
If both BS1 and BS0 are “High” at read, write, row active and precharge, bank D is selected.
If A10/AP is “High” at row precharge, BS1 and BS0 is ignored and all banks are selected.
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. 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)
