These separated data are inputted to the memories 1 and 2 with switching and also read alternately from both memories 1 and 2. In this case, the input/output data switch control means 6 and 7 decides whether the input/output data switching should be carried out or not to both memories based on the information showing the memory under designation of a writing operation, an input/output memory selection signal, and an input/ output data reset signal. Thus the input/output data are switched to both memories 1 and 2. In such a constitution, a zero address register is omitted and the circuit scale is reduced.
