More Information
Summary:Techniques are presented that allow a memory card operable according to two protocols (such as a legacy protocol and newer protocol), and having a corresponding dual interface, to be used with hosts that support the new protocol as well as having backward compatibility with legacy hosts, while preventing the use of legacy cards with hosts that support the new protocol but do not support the legacy protocol. The card that supports the new protocol has a similar form factor to the legacy card, includes an indentation. A host that supports the new, but not the legacy, type card includes a mechanical structure within the attachment slot that, based on the card indentation, can distinguish the card types and prevent the non-supported card from being attached.
