ABSTRACT:
A portable, non-volatile read/write memory module includes a battery for providing standby power that is coupled to a monolithic integrated circuit. Five terminals of the module are removably connected to a host electronic system for transfer of data to and from the module. One of the terminals is a chip enable input that may optionally be used for providing operating power to the monolithic integrated circuit. The monolithic integrated circuit further includes control circuitry that may optionally be coded for providing a security feature for access to data stored in the memory module.
