Abstract: The miniature card uses an Attribute Information Structure (AIS) for card recognition. The PC Card specification uses a Card Information Structure (CIS) for card recognition. The dual information structure definition provides a mechanism to allow a miniature card to be recognized and functional in both a PC Card environment and miniature card environment. The dual information structure mechanism incorporates the AIS structure into the CIS structure within the miniature card, thus allowing a card to be recognized and function in both environments.

Abstract: An apparatus and method for a memory card bus design. The memory card bus design allows the memory card to interface with a wide variety of systems such as, hand held consumer products and personal computers. The bus design provides a simple interface for both volatile and non-volatile memories which allows data to be exchanged between the memory device and another system.

Abstract: A method and apparatus for interfacing a memory card with a system having a smaller bus width while maintaining its interchangeability with other systems having larger bus widths. The host accesses data stored in the memory card using an interleaving scheme, such as a two-way interleaving scheme. The host provides a first enable signal and a second enable signal. In response to the first enable signal, data is accessed from a first section of the addressed memory location, and in response to the second enable signal, data is accessed from a second section of the addressed memory location. The first section of the addressed memory location may store even data bytes and the second section of the addressed memory location may store odd data bytes. The host may only access one section of the selected memory location at a time when using the interleaving scheme.
