Systems and methods of obtaining status information from PCMCIA cards installed within host computers are provided. A PCMCIA card includes a processor having a static random access memory (SRAM) attribute memory address space implemented therewithin. The SRAM attribute memory address space includes a Card Information Structure (CIS) that is readable by the host computer. Owner control signals provide an indication of ownership of the SRAM attribute memory address space. A host computer reads PCMCIA card status information from a CIS when an owner control signal indicates host computer ownership of the SRAM attribute memory address space. A host computer is prevented from reading status information from a CIS when an owner control signal indicates PCMCIA card processor ownership of a SRAM attribute memory address space.
A method of obtaining status information from a peripheral device card installed within a peripheral device interface of a host device, wherein the peripheral device card includes a processor having a static random access memory (SRAM) attribute memory address space implemented therewithin, and wherein the SRAM attribute memory address space comprises a Card Information Structure (CIS) that is readable by the host device, the method comprising the steps of:
