Memory capacity switching method and semiconductor device to which the

Abstract

A memory capacity switching method for switching capacities of an accessible memory in a semiconductor device 1 which comprises on a single chip the memory 2, a capacity switching signal generating circuit 4 for generating a capacity switching signal, and a control circuit 5 for switching capacities of the memory on the basis of the capacity switching signal. The method comprises the step of setting the capacity switching signal from the capacity switching signal generating circuit 4 either to 0 or to 1 causing the control circuit to switch the memory capacities as needed. The method and the semiconductor device for use therewith combine to shorten the time required for semiconductor device development and to reduce costs in fabricating the device.
