US 7,065,591 B2 · Reconfigurable flash media reader system

Abstract

A reconfigurable flash media reader system provides a flash media reader that accepts both asynchronous and synchronous flash media cards. The reader identifies the card type of the inserted flash media card and notifies the host computer of the card type. The host computer has a list of interface information for different types of flash media cards and references the card type in the list and sets the proper baud rate on the reader. If the flash media card is a synchronous card, data that is to written into the flash media card is gathered and converted to the proper card IO strobes for the card type which are interleaved with the proper card clock strobes for the card type into a bit stream in a bulk transfer packet. The reader extracts the data bit stream from said bulk transfer packet and clocks the data bit stream into the flash media card using the baud rate as a reference clock.

Dependent claims

A method, comprising:

identifying a flash media card type inserted in a flash media reader;
configuring said flash media reader according to said flash media card type using a host computer via a communication link;
converting data to be written into said flash media card to card IO strobes for said card type;
interleaving said converted card IO strobes with card clock strobes for said card type into a bulk transfer packet if said card is a synchronous card;
and
transmitting said bulk transfer packet via said communication link to said flash media reader.
