摘要： A mass storage memory system and a method for re-allocating memory partition space is provided. The storage system includes a memory controller with a microprocessor that is adapted to receive data via a logical interface from a host system; a first memory partition with a system area and a data area; and a second memory partition with a system area and a data area; wherein the memory controller re-allocates memory space from the second memory partition to the first memory partition that is either full or has reached a threshold value, by using a virtual block address for the system area and the data area such that the system area and the data area appear contiguous to the host system.

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.
