Abstract: A memory card identification method and a mobile device are provided. The memory card identification method includes: sending an initialization command of a first-type memory card communications protocol to a to-be-identified memory card; detecting whether there is a response in a command pin of the memory card; and identifying the memory card as a first-type memory card or a second-type memory card based on a response status of the command pin.

Abstract: The present application discloses a storage device and a data processing method thereof. The method includes: receiving a data processing command; converting the data processing command into a plurality of groups of subcommands, wherein each group of subcommands includes at least one subcommand: caching each group of subcommands in a corresponding storage element: and submitting the subcommands in each storage element to a storage medium controller in sequence to execute the subcommands, wherein submitting, in response to at least two subcommands existing in the storage element, a data address of a subsequent subcommand and a previous subcommand simultaneously. By means of the described way, the data processing efficiency of the storage device may be improved.

Abstract: A storage device and a storage device operation method are provided. The storage device has a processing capability for a first communications protocol and a processing capability for a second communications protocol. The method includes: receiving an adaptive command (110); and identifying the adaptive command, and determining, according to the adaptive command, to execute the first communications protocol or the second communications protocol for an operation (120). According to the foregoing method, the storage device can perform an adaptive operation between different communications protocols.

Abstract: A memory card includes a packaging board and a plurality of contacts disposed on one side surface of the packaging board, where the contacts include a power supply contact, a grounding contact, and a detection contact. The detection contact is disposed adjacent to one of the power supply contact or the grounding contact and is suspended or electrically connected to the other of the power supply contact or the grounding contact.

Abstract: The present invention is adapted to data storage technology field, and provides a reading/writing control method and system for nonvolatile memory, the method including the following steps: dividing valid blocks in the nonvolatile memory into different zones, the zones including at least one data zone having fixed number of valid blocks and one exchange zone having at least two valid blocks; creating a mapping table of logic blocks and physical blocks in each zone; establishing a mapping table of logic pages and physical pages in the blocks based on redundant area information of pages in the blocks, and storing the mapping table of the logic blocks and physical blocks in each zone and the mapping table of logic pages and physical pages in each block in a private data area; and writing data segments in an idle page of the blocks of the data zones in sequence, or reading data segments from valid pages in the data zones, thus the data reading/writing speed and efficiency is promoted.
