ABSTRACT:
A method and device for hiding refresh operations during accesses to sub-arrays of a pseudo-static memory device. By refreshing sub-arrayjwhile filling the row Ri(where i≠j) corresponding to sub-arrayi, refresh operations can be performed without risking that a read request will interrupt the refresh operation. Additional refresh operations of sub-arrayican be performed serially with the operations of filling the row Riwithout delaying the overall burst read or write operation if the burst is made sufficiently long.
