Selective extension of a fine granularity mode for memory refresh operations

Abstract:

Control circuitry may operate to refresh memory banks and determine that a memory bank was not refreshed within a threshold time duration from the current time. The control circuitry may extend a duration of an operational mode in response to determining that the memory bank was not refreshed within the threshold time duration. In response to extending the duration of the operational mode, the control circuitry may refresh the second memory bank without refreshing the first memory bank.
