Abstract
An object is to enable a semiconductor integrated circuit device to perform the second action, without waiting for the first action to finish after the first action starts. Aside from a resistor containing input signal pulses, an input signal pulses recognizing circuit is provided so that it detects signal input which activates the second action during the execution of the first action and controls driving with the result thereof. In a device such as EEPROM, CPU moves on the next action after writing operation starts. CPU checks periodically whether writing operation is being conducted or has finished, so that the processing ability of a whole device can be improved to the maximum.
