Abstract

PURPOSE:To perform efficiently the control dependent upon a CPU to shorten the whole of the operation time by providing an oscillator which refreshes a data register. CONSTITUTION:Main memory unit 1, dynamic memory register 2 and CPU4 are provided, and register 2 is controlled by clock signals from CPU4. Then, oscillator 7 which refreshes data of register 2 is used to supply the output of oscillator 7 to register 2 when it is unnecesary that register 2 is synchronized with clock signals from CPU4.
