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 write” function will be enabled.
