Abstract
A pseudo SRAM integrated circuit device is achieved. The device comprises, first, a memory array comprising a plurality of dynamic storage cells. Finally, an access controller is included. The access controller provides read and write access to the memory array from an external device. The access controller performance is compatible with a standard SRAM memory device. The access controller enables a partial data retention mode comprising selective refreshing of at least one part of the memory array and non-refreshing of at least one other part of the memory array.
