    Abstract: 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.

    Abstract translation: 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,该状态位标识其在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。

    Abstract: Methods and apparatus for enabling updates to data structures to be scheduled are disclosed. According to one aspect of the present invention, a method for operating a memory system with a non-volatile memory that includes a plurality of physical blocks and a plurality of data structures including an erase count block involves determining when contents of at least one data structure is to be updated (316). A request to update the contents of the data structure is queued (318) or scheduled when it is determined that the contents are to be updated, and the request is executed (320) when it effectively reaches the top of the queue.

    Abstract: Methods and apparatus for splitting a single logical block into two or more physical blocks are disclosed. According to one aspect of the present invention, a method for associating a plurality of physical blocks of a non-volatile memory with a logical block that includes of logical block elements involves grouping the logical block elements into at least a first logical set and a second logical set. Data associated with the first logical set is provided to a first physical block. And data associated with the second logical set is provided to a second physical block.

    Abstract: Methods and apparatus for efficiently enabling pages within a block to be accessed are disclosed. According to one aspect of the present invention, a method for writing data into a first block in a non-volatile memory which includes pages that are grouped into groups which each include two or more pages involves determining when a first group is available to receive the data. When it is determined that the first group is available to receive the data, the data is written into a first page included in the first group. The method also includes determining when a second group is available to receive the data if it is determined that the first group is not available to receive the data, and writing the data into a second page included in the second group when it is determined that the second group is available to receive the data.
