Notes :
1. Maximum burst refresh cycle : 8
2. The specific requirement is that DQS be valid(High or 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 tDQSS.
3. 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.
4. A write command can be applied with tRCD satisfied after this command.
5. For registered DIMMs, tCL and tCH are
45% of the period including both the half period jitter (tJIT(HP)) of the PLL
and the half period jitter due to crosstalk (tJIT(crosstalk)) on the DIMM.
