If both BA1 is “High” and BA0 is “Low” at read ,write , row active and precharge ,bank C is selected.
If both BA1 and BA0 are “High” at read ,write , row active and precharge ,bank D is selected
If A10/AP is “High” at row precharge , BA1 and BA0 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 t
RP
after the end of burst.
6.Burst stop command is valid at every burst length.
7.DQM sampled at positive going edge of a CLK and masks the data-in at the very CLK (write DQM latency is 0), but
makes Hi-Z state the data-out of 2 CLK cycles after.(Read DQM latency is 2)

POWER UP SEQUENCE
1.Apply power and start clock, Attempt to maintain CKE = ”H”, DQM = ”H” and the other pin are NOP condition at the inputs.
2. Maintain stable power , stable clock and NOP input condition for a minimum of 200us.
3. Issue precharge commands for all banks of the devices.
4. Issue 2 or more auto-refresh commands.
5. Issue mode register set command to initialize the mode register.
cf.) Sequence of 4 & 5 is regardless of the order.
The device is now ready for normal operation.
Note : 1. RFU(Reserved for future use) should stay “0” during MRS cycle.
2. If A9 is high during MRS cycle, “ Burst Read single Bit Write” function will be enabled.
3. The full column burst (256 bit) is available only at sequential mode of burst type.
