Apply power and start clock. Must maintain CKE= "H", DQM= "H" and the other pins 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 a 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. If A9 is high during MRS cycle, "Burst Read Single Bit Write" function will be enabled. 2. RFU (Reserved for future use) should stay "0" during MRS cycle.
