Abstract
A memory performs a hidden refresh only at the end of a read operation or when the memory is disabled but is supposed to retain data in the disabled state. When the memory is in the enabled state, the refresh is not performed at the end of any operation other than read. This is done to ensure that execution of any memory access command will not be delayed by a refresh as long as the user follows certain timing rules. Other embodiments arc also provided.
