Abstract

See full text

A non-volatile memory module includes a volatile memory circuit; an interface to a reference voltage source external to the module providing an external reference voltage to the volatile memory circuit by which the volatile memory circuit and external devices may communicate reliably at high speeds; an internal reference voltage generator; and a control circuit adapted to cause the volatile memory circuit to be decoupled from using the external reference voltage and coupled to using a reference voltage from the internal reference voltage generator upon the non-volatile memory module ceasing to draw power from an external power source.
