记忆卡存取装置、其控制方法与记忆卡存取系统;Memory card access device, control method thereof, and memory card access system

摘要

本发明揭露了记忆卡存取装置、其控制方法与记忆卡存取系统。所述装置包含：一记忆卡介面电路，用来依据一记忆卡读取讯号产生一记忆卡读取资料，或用来依据一记忆卡写入资料产生一记忆卡写入讯号；一主机介面电路，用来依据一主机读取讯号产生一主机读取资料，或用来依据一主机写入资料产生一主机写入讯号；以及一控制电路，耦接该记忆卡介面电路与该主机介面电路，能够依据一预设协定处理该记忆卡读取资料以产生该主机写入资料，或依据该预设协定处理该主机读取资料以产生该记忆卡写入资料，藉此将一记忆卡做为一快取装置。; a host interface circuit to generate host reading data according to host reading signal or generate host writing data according to host writing signal; and a control circuit, coupled to the memory card and host interface circuits respectively, capable of generating the host writing data by processing the memory card reading data according to a predetermined protocol or generating the memory card writing data by processing the host reading data according to the predetermined protocol, so as to treat a memory card as a cache device.
