ABSTRACT:
A semiconductor memory is provided with automatic refresh means including a timer, a refresh counter and a refresh buffer each formed on a semiconductor chip mounted with an asynchronous memory, for automatically performing a periodic refresh operation on the basis of a basic clock signal which is generated in response to the detection of a logical change in the output of the refresh counter. The automatic refresh counter includes means for performing one of a read operation and a write operation which are based upon a regular address signal asynchronous with the periodic refresh operation, in preference to the periodic refresh operation.
