Abstract

PURPOSE:To enable to effectively process the refresh and the readout/write-in instruction, when they are instructed simultaneously to the memory unit using the memory element requiring refresh. CONSTITUTION:The readout/write-in(R/W) instruction and the refresh(REF) instruction are tentatively held to the registers 34, 35 via the AND circuits 31, 32, and the block coincidence signal representing the concidence of the both instructions, R/W block and REF block is stored in the register 36 via the AND circuit 33. R/W signal is delivered to the memory circuits 20 to 21 for the output of the register 34 and the inversion output of the register 36 via the AND circuit 40. In this case, R/W signal and REF signal are processed so that they can not be duplicated in the same block by controlling the register 34 through the output of the register 36 via the registers 37, 38, 39 and through the AND circuit 42 taking R/W inversion signal as one input.
