IPC: G11C11/406
Filed: 2001-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor storage device which operates at a SRAM specification and in which a memory cycle can be shortened compared with a conventional case without the delay of regular access by the influence of refresh. SOLUTION: An ATD circuit 4 receives the change of an address and generates a one shot pulse in an address change detection signal ATD after an address queue period elapses. In the case of a writing request, a writing enable signal/WE, is made to fall in the address queue period. Writing or reading is preformed from the rise of the one shot pulse. In the case of writing, late writing by using the address and data, which are given at the time of the writing request just before, is preformed. Then, refreshing is performed until the address queue period of the subsequent memory cycle terminates from the fall of the one shot pulse. For late writing at the time of the new writing request, the address and data are taken into register circuits 3 and 12 with the rise of the writing enable signal/WE.
