    Abstract: 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.

    Abstract translation: 本发明提出了用于在主机和存储卡之间传输应用程序特定指令的技术。 用于应用程序特定协议的命令与用于在主机与存储卡之间进行通信的传输协议的数据部分中的签名一起嵌入。 这允许在传输协议中缺少相应命令的特定于应用的命令的传输仍然在该协议中传输。 该方法可以在主机端在设备驱动程序级别或文件级别上实现。 为了在应用专用协议中实现读取命令，具有嵌入式读取命令的第一协议中的写入命令首先被发送到逻辑地址，然后是第二读取命令到同一逻辑地址。

    Abstract: Method and apparatus for performing wear leveling in a non-volatile memory system are disclosed. According to one aspect of the present invention, one method for processing elements included in a non-volatile memory of a memory system includes obtaining erase counts associated with elements and grouping a number of the elements into a first set. Each element has an associated erase count that substantially indicates a number of times the element has been erased. Grouping the number of elements into the first set includes selecting elements included in the plurality of elements which have the lowest associated erase counts of the erase counts associated with the plurality of elements. The method also includes storing the erase counts associated with the first set in a memory component substantially within a table.

    Abstract: Methods and apparatus for managing erase counts in a non-volatile memory system. According to one aspect of the present invention, a method for initializing an erase count block in a system memory of a non-volatile memory system, the non-volatile memory system which includes a non-volatile memory involves allocating a plurality of pages within the system memory that are divided into a plurality of entries. Each entry of the plurality of entries has an associated block in the non-volatile memory. The method also includes identifying usable blocks which are suitable for use in accepting user data, and storing values in each entry which is associated with a usable block. Storing the values in each entry which is associated with a usable block substantially identifies the usable block as being usable.
