1. When using Self Refresh mode, the following refresh operations must be performed to ensure proper DRAM operation:
If row addresses are being refreshed in an EVENLY DISTRIBUTED manner over the refresh interval using CBR refresh cycles,
then only one CBR cycle must be performed immediately after exit from Self Refresh.
If row addresses are being refreshed in any other manner (ROR- Distributed/Burst; or CBR-Burst) over the refresh interval, then a
full set of row refreshes must be performed immediately before entry to and immediately after exit from Self Refresh.
