(EN) IDENTIFICATION METHOD FOR MEMORY CARD, AND MOBILE DEVICE
(FR) PROCÉDÉ D’IDENTIFICATION POUR CARTE MÉMOIRE, ET DISPOSITIF MOBILE

Abstract
(EN)
An identification method for a memory card, and a mobile device. The identification method for a memory card comprises: pulling down the potential of a command pin of a memory card to be identified (11); detecting whether there is a response in a data pin of the memory card (12); and identifying, according to a response situation of the data pin, the memory card as a first-class memory card or a second-class memory card (13). By means of the method, the identification flow of the memory card can be shortened, and the identification speed can be accelerated.
(FR)
La présente invention concerne un procédé d’identification pour une carte mémoire, et un dispositif mobile. Le procédé d’identification pour une carte mémoire comprend : le tirage vers le bas du potentiel d’une broche de commande d’une carte mémoire à identifier (11) ; le fait de détecter s’il y a une réponse dans une broche de données de la carte mémoire (12) ; et l’identification, selon une situation de réponse de la broche de données, de la carte mémoire en tant que carte mémoire de première classe ou en tant que carte mémoire de seconde classe (13). Le procédé permet de raccourci le flux d’identification de la carte mémoire et d’accélérer la vitesse d’identification.
