Abstract

The invention discloses a memory card identification method and mobile equipment. The memory card identification method comprises the steps: reducing the potential of a command pin of a to-be-identified memory card; detecting whether a response exists in the data pin of the memory card; and identifying the memory card as a first type memory card or a second type memory card according to the response condition of the data pin. By means of the mode, the recognition process of the memory card can be shortened, and the recognition speed is increased.

Description

technical field [0001] The present application relates to the field of storage technology, in particular to a storage card identification method and a mobile device. Background technique [0002] Due to its large storage capacity, easy portability, and fast reading and writing speeds, memory cards are supported by more and more terminal devices. At present, after the memory card is inserted, the terminal device loads data to the memory card through an identification program to realize the identification of the memory card. [0003] Taking the MMC card and SD card as an example, when identifying the MMC card and the SD card, the CMD8 command and the ACMD41 command are usually used to determine whether the SD card responds to identify the SD card. This way needs two steps to realize, the speed is slower, and the recognition efficiency is lower. Contents of the invention [0004] The present application mainly provides an identification method of a memory card and a mobile ...
