Abstract

The invention provides a read-write control system and method for a memory card. The read-write control system comprises a memory card interface, a host system interface and a control device. When the memory card operates according to a first communication protocol, the memory card interface is electrically connected with the host system interface through a second selector, a bridging device and a first selector. When the memory card operates according to a second communication protocol, the memory card interface is electrically connected with the host system interface through the second selector, and the memory card interface is also electrically connected with the host system interface through the first selector.

Description

technical field [0001] The present invention relates to an electronic device and its method, in particular to a memory card read-write control system and its method. Background technique [0002] With the rapid development of information technology, the application of electronic products is becoming more and more popular, such as notebook computers, mobile phones, tablet computers and other handheld electronic devices can be seen everywhere. Since the characteristics of these electronic devices are that they can be carried around and used anytime and anywhere, and in order to enable various electronic devices to be connected to each other for a large amount of data transmission, the above-mentioned memory card is usually inserted into the card reader to make the above-mentioned The electronic product can erase and write the data of the memory card, so as to expand the memory storage capacity of the electronic product. [0003] However, as the data access speed of the memory...
