Abstract
A flash memory card includes a differential datapath that enables communications between the flash memory card and a host device to be performed using differential signals. The differential datapath can translate between the differential signals and card-specific signals that control read/write operations to the memory array of the flash memory card. The card-specific signals can be standard MultiMediaCard, Secure-Digital card, Memory Stick, or CompactFlash card signals, among others. A host device that provides differential data transfer capability can include a similar differential datapath. By using differential data transfer rather than conventional clocked data transfer, overall data bandwidth between a flash memory card and a host device can be significantly increased, while simultaneously decreasing power consumption and pin requirements.
