Abstract

An universal and detachable low cost data storage system adaptable to different communication protocols. Particularly, the storage system can be attached to hosts running different communication protocols such as MultiMediaCard and Serial Peripheral Interface. The storage system automatically selects the protocol in response to the host requirements such that the entire protocol selection process will be transparent to the host.

Claims

1. A memory card for connecting to a master, comprising:

a plurality of storage elements; and

an interface for communicating with the master, wherein data and commands are transferred between the card and the master;

wherein said card is capable of adapting to the master running one protocol selected from a plurality of communication protocols.
