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 memory device contains control structures that allow media content to be stored securely and distributed in a manner envisioned by the content owner, or service providers involved in the distribution. A wide variety of different avenues become available for distributing media content using such memory devices, such as where the devices contain one or more of the following: abridged preview media content, encrypted unabridged media content, prepaid content, rights and/or rules governing access to such content. The memory device has a type of control structures that enable a service provider (who can also be the content owner) to create a secure environment for media content distribution where end users and terminals register with the service provider, and gain access to the content in a manner controlled by the service provider. The various components to be loaded (e.g. abridged preview media content, encrypted unabridged media content, prepaid content, rights and/or rules governing access to such content) may be generated and loaded in a secure and efficient manner.

摘要： A method of controlling data access to non-volatile memory is disclosed. The method includes storing a data file in a non-volatile memory. The non-volatile memory includes a memory array including a plurality of address ranges one or more of which corresponding to a protected portion of the memory array and one or more of which corresponding to an unprotected portion of the memory array. The method also includes communicating to a host device an indication that a memory request with respect to the protected portion of the memory array is denied. The indication is communicated for instructing the host device to avoid a timeout when the memory request is denied.

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.
摘要翻译：本发明提供了用于在主机和存储卡之间传送应用特定指令的技术。应用专用协议的命令与用于在主机之间进行通信的传输协议的数据部分中的签名一起被嵌入。这允许在传输协议中缺少相应命令的应用专用命令的传输仍然以该协议传输。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，首先将具有嵌入式读取命令的第一协议中的写入命令发送到逻辑地址，然后发送到相同逻辑地址的第二读取命令。

摘要： Methods and apparatus for enabling a power up process of a non-volatile memory to occur efficiently are disclosed. According to one aspect of the present invention, a method for utilizing a memory system that has a non-volatile memory with at least one reserved memory area includes providing power to the memory system, initializing the non-volatile memory, and writing a first signature into the reserved memory area. The first signature is arranged to indicate that the memory system was successfully initialized. In one embodiment, the method also includes executing a power down process on the memory system, and writing a second signature into the reserved memory area which indicates that the power down process has been executed.

摘要： One or more rights objects (RO) files may be used for storing RO's preferably in the protected area available only to authenticated users. A RO navigation file is stored preferably in an unprotected public area containing status bits, where each status bit identifies whether a location in a RO file contains a valid RO or not. Preferably, there is a one-to-one correspondence between the location for a RO in a RO file and a location in the RO navigation file for the status bit which identifies whether its corresponding location in the RO file contains a valid RO or not. Whether a particular location in a RO file contains a valid RO or not can be found by checking its corresponding status bit in the RO navigation file. By finding out whether a particular location in a RO file contains a valid RO or not in this manner, it is possible to delete ROs without having to go through an authentication process. The process of finding an empty slot in the RO file for storing a new RO is also simplified. This greatly increases the efficiency of RO management. A similar system may be used for management of content encryption/encryption keys for protecting content files.
摘要翻译：可以使用一个或多个权限对象（RO）文件来存储RO，优选地在仅对经认证的用户可用的保护区域中。 RO导航文件优选地存储在包含状态位的未受保护的公共区域中，其中每个状态位识别RO文件中的位置是否包含有效的RO。优选地，在RO文件中的RO的位置与用于状态位的RO导航文件中的位置之间存在一一对应关系，其识别其在RO文件中的相应位置是否包含有效的RO。通过检查RO导航文件中相应的状态位，可以找到RO文件中的特定位置是否包含有效的RO。通过查找RO文件中的特定位置是否包含有效的RO，以这种方式，可以删除RO而无需经过身份验证过程。在RO文件中找到用于存储新的RO的空槽的过程也被简化。这大大提高了RO管理的效率。类似的系统可以用于管理用于保护内容文件的内容加密/加密密钥。

摘要： Methods and apparatus for maintaining an average erase count in a system memory of a non-volatile memory system are disclosed. According to one aspect of the present invention, a method for determining an average number of times each block of a number of blocks within a non-volatile memory of a memory system has been erased includes obtaining an erase count for each block that indicates a number of times each block has been erased. Once all the erase counts have been obtained, the erase counts are summed, and an average erase count that indicates the average number of times each block of the number of blocks has been erased is created by substantially dividing the sum by the number of blocks.
