Embedded multimedia card (eMMC), eMMC system, and methods of operation

摘要

An embedded multimedia card (eMMC) communicating with a host includes; a latch circuit that receives and latches a data signal according to either a first edge or a second edge of a clock to thereby generate a latched data signal, and a start bit detector that detects in the latched data signal a start bit and provides a valid data signal from a portion of the latched data signal following the start bit.

1. An embedded multimedia card (eMMC) communicating with a host, the eMMC comprising:
a latch circuit configured to receive and latch a data signal according to one of a first edge and a second edge of a clock to generate a latched data signal; and a start bit detector configured to detect a start bit in the latched data signal, and provide, in response to detecting the start bit, a valid data signal from a portion of the latched data signal following the start bit.
