Notes:

1. Device must be in the “All banks idle” state prior to entering Self Refresh mode .

2. ODT must be turned off t AOFD before entering Self Refresh mode, and can be turned on again when t XSRD timing is

satisfied.

3. t XSRD is applied for a Read or a Read with Auto-precharge command. t XSNR is applied for any command except a Read or a

Read with Auto-precharge command.
