Abstract
A structure for handling the refresh of a DRAM array so that the refresh has no effect on the external access. A system clock signal initiates activation and deactivation of elements of the DRAM array using a sequencer which subdivides each system clock signal period into three parts, thus providing four control signals fixed phase relationship per clock period.
