Abstract
An apparatus may be used with a computer system having a PCMCIA interface. The apparatus employs a DRAM device and logic for converting the PCMCIA SRAM control signals into DRAM control signals, so as to permit the communication of data and control signals between the computer system and the DRAM device. The apparatus further provides controls for refreshing the DRAM device, and for arbitrating between the functions of refreshing the DRAM and providing for communication between the DRAM and the computer system. The apparatus further provides the power management functions required for operating a DRAM device in a PCMCIA environment.
