Abstract
A memory cartridge having a plurality of dynamic memory units includes an access conversion circuit which converts a static access signal into its inverted signal and an access control circuit which controllably switches between a signal for refreshing each dynamic unit and a signal for external access. The memory cartridge also includes a power switching circuit which switches power from an internal power supply to an external power supply when the memory cartridge is mounted to an external device.
