Abstract
A refresh circuit is used for refreshing or masking from refresh non-contiguous subarrays in an integrated circuit memory array. At the initiation of each masked refresh cycle the address inputs, which normally are ignored, are evaluated to indicate which subarrays should be refreshed and which should be not refreshed. Power is saved due to the flexibility in determining which subarrays are refreshed at each new refresh cycle.
