1. Apply power and start clock, Attempt to maintain CKE= "H", DQM= "H" and the other pins are NOP condition at the inputs.
2. Power is applied to VDD and VDDQ (simultaneously).
3. Maintain stable power, stable clock and NOP input condition for a minimum of 200us.
4. Issue precharge commands for all banks of the devices.
5. Issue 2 or more auto-refresh commands.
6. Issue a mode register set command to initialize the mode register.
Note :
1. In order to assert normal MRS, BA0 and BA1 should set "0" absolutely.
