3. The specific requirement is that DQS be valid(High-Low) on or before this CK edge. The case shown(DQS going
from High_Z to logic Low) applies when no writes were previously in progress on the bus. If a previous write was
in progress, DQS could be High at this time, depending on t
DQSS.
4. The maximum limit for this parameter is not a device limit. The device will operate with a great value for this
parameter, but system performance (bus turnaround) will degrade accordingly.

Notes :
1. OP Code : Operand code

2. MRS can be issued only at all banks precharge state.
A new command can be issued after 2 CLK cycles of MRS.
3. Auto refresh functions are as same as CBR refresh of DRAM.
The automatical precharge without row precharge command is meant by "Auto".
Auto/self refresh can be issued only at all banks precharge state.
