a dynamic power management device for supplying power to a solid state memory integrated circuit includes power control circuitry for supplying a variable voltage to the memory integrated circuit and logic control circuitry responsive to data access activity for generating address and control signals for the memory integrated circuit and for controlling the power control circuitry to supply power to the memory integrated circuit sufficient to maintain memory information in the memory integrated circuit during periods of no data access activity and sufficient to exchange memory information with the memory integrated circuit during periods of data access activity . power consumption of the memory integrated circuit is thereby curtailed .
