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