ABSTRACT:
A memory controller and system for providing access to PCMCIA standard memory cards and non-standard memory cards. Non-standard memory cards are memory cards that are compliant with PCMCIA standards for sockets and are non-compliant in other respects. The memory controller has a register for storing a code that indicates whether a memory card is a PCMCIA card or a non-standard memory card. An access control circuit in the memory controller activates and deactivates memory card control signals at times required by the memory card and as indicated by the memory card type. An acknowledge control circuit generates an acknowledge signal to a requesting processor at a time prescribed by the type of memory card.
