Asynchronous semiconductor memory device
 An asynchronous semiconductor memory device having an address change detector which generates a pulse with a specified pulse width by detecting change in an address signal and a component for holding an internal circuit in the non-operating condition responding to the address signal for a period when said pulse does not exist. The internal circuit is caused not to operate in response to an unwanted address signal generated in the course of the change of the address signal input from an external device, or in response to an unwanted address signal generated by noise. Thereby power consumption is reduced.
