摘要： A file system and method of file access are disclosed. In a particular embodiment, a method is performed at a host device coupled to a non-volatile memory, where the host device includes a memory having a first file data structure. A first directory entry in a file directory of a file system is located where the first directory entry corresponds to a first file stored in the non-volatile memory. First data associated with the first directory entry, including first location data indicating a location of the first file in the non-volatile memory, is retrieved and stored in the first file data structure. A request to open the first file is received. In response, the first location data of the first file is retrieved from the first file data structure and data of the first file from the non-volatile memory is read. First metadata associated with the first file is extracted from the data read from the non-volatile memory.

摘要： The present invention presents techniques for transmitting application specific instruction between a host and a memory card. The commands for the application specific protocol are embedded along with a signature in the data portion of a transmission protocol that is used to communicate between the host the memory card. This allows for the transmission of application specific commands that lack a corresponding command in the transmission protocol to still be transmitted in that protocol. The method can be implemented on the host side either at the device driver level or the file level. In order to implement a read command in the application specific protocol, a write command in the first protocol with an embedded read command is first sent to a logical address, followed by a second read command to the same logical address.
