CKE FUNCTION TRUTH TABLE
Note :
When CKE=L, all DQ and DQS must be in Hi-Z state.
1. CKE and /CS must be kept high for a minimum of 200 stable input clocks before issuing any command.
2. All command can be stored after 2 clocks from low to high transition of CKE.
3. Illegal if CLK is suspended or stopped during the power down mode.
4. Self refresh can be entered only from the all banks idle state.
5. Disabling CLK may cause malfunction of any bank which is in active state.
