Abstract

A semiconductor file memory, intended for use as an external memory of an information processor such as an arithmetic processor, including an interface for transacting data with the information processor, a plurality of memory units each including semiconductor memory devices mounted on a substrate and having identical terminal assignments in connection commonly to a bus of the interface through a connector, a control circuit unit having identical terminal assignments for the connectors of the memory units and operating to control the memory units by taking the place of at least one of the memory units, and a selection circuit for selecting a memory unit or control circuit unit out of the memory units and the control unit which has taken the place of the memory unit in response to signal from the interface.
