とを特徴とする電子計算機。 An electronic computer consisting of a central processing unit and multiple memory units has a memory selection circuit that outputs a reset signal, a memory selection signal, and a shift clock in order to select which memory unit is valid for the central processing unit. In order to indicate to the unit that its own memory unit is valid, it is reset by a reset signal output from the central processing unit, and a memory selection signal or a memory valid signal of another memory unit is taken in by a shift clock and the memory of its own memory unit is reset. An electronic computer characterized by having a memory valid signal output circuit that outputs a valid signal.
