Memory card, digital device, and method of data interfacing between memory card and digital device

摘要

A memory card includes improved data transmission speed. A digital device is capable of data interfacing with memory card for a high speed, and a method for a high-speed data interface between the memory card and the digital device. The memory card includes a memory unit storing data and an oscillator generating a first clock signal. The memory card includes an interface transmitting the data synchronously read with the first clock signal to host connected therewith and receiving from the host a recording data synchronously transmitted from the host with a second clock signal.
