摘要：
A memory including an array of memory cells and a control circuit. The control circuit is configured to control partial array self refreshes and to switch from one partial array self refresh to another partial array self refresh. Data in memory cells that are refreshed via the one partial array self refresh and refreshed via the other partial array self refresh is retained in the memory cells from before a first switch from the one partial array self refresh to the other partial array self refresh to after the first switch.
