Abstract
A memory card reading method applied to an electronic device, includes: detecting a specification information of a memory card, wherein the specification information includes a transfer speed of the memory; and controlling according to the specification information a reader to host interface to operate in a first operating mode or a second operating mode for reading the memory card, wherein the first operating mode and the second operating mode correspond to different data transfer speeds.
Claims14
A memory card reading method applied to an electronic device, comprising:
- detecting a specification information of a memory card, wherein the specification information comprises a transfer speed of the memory card;
- controlling according to the specification information a reader-to-host interface to operate under a first operating mode or a second operating mode which is selected as a current operating mode for reading the memory card, wherein the first operating mode and the second operating mode correspond to different data transfer speeds,
- determining if a status of the reader-to-host interface or the electronic device corresponds to a first condition;
- and
- when the status corresponds to the first condition, changing the current operating mode for the reader-to-host interface to another operating mode with a different data transfer speed than the current operating mode.
A memory card reading method applied to an electronic device, comprising:
- controlling according to a specification information of a memory card a reader-to-host interface to operate under a first operating mode which is selected as a current operating mode for reading the to read a memory card;
- determining if a status of the electronic device corresponds to a condition;
- when the status corresponds to the condition, changing the current operating mode for the reader-to-host interface to a second operating mode with a different data transfer speed than the current operating mode.
A memory card reading system, comprising:
- a card reading circuit, arranged to detect a specification information of a memory card, wherein the specification information comprises a transfer speed of the memory card;
- and
- a processing circuit, arranged to control according to the specification information a reader-to-host interface to operate under a first operating mode or a second operating mode which is selected as a current operating mode for reading the memory card, wherein the first operating mode and the second operating mode have different data transfer speeds,
- wherein when a status of the reader-to-host interface corresponds to a first condition, the processing circuit is further arranged to change the current operating mode for the reader-to-host interface to another operating mode with a different data transfer speed than the current operating mode.
