Note: The Power Down Mode is entered by asserting CKE "low".
All Input/Output buffers (except CKE buffers) are turned off in the Power Down mode.
When CKE goes high, command input must be No operation at next CLK rising edge.
Violating refresh requirements during power-down may result in a loss of data.
