Abstract

PURPOSE:To shorten a write time of data, by constituting so that all memory units enter an address area of the same memory unit, in case when the same data is written in all addresses of the memory. CONSTITUTION:At first, a processor 11 accesses prescribed address signals A0- A9 of a low-order 10 bits of a selected memory unit 140, and writes prescribed write data D0-D15 through a data bus. Subsequently, the microprocessor 11 sends out prescribed addresses A0-A9 and initial value data D0-D15 to memory units 140-14n through an address bus and a data bus, respectively. Also, a memory map switching circuit 13 receives an interruption receiving signal, sets all chip selecting signals CE0-CEn to a selected state, and applies then to the memory units 140-14n. In this way, all the memory units 140-14n enter the same address area.
