    摘要： Methods and apparatus for allowing tables to be adaptively backed up 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 reserved memory area, a plurality of physical blocks and a plurality of data structures including an erase count block involves determining when contents associated with at least one data structure of the plurality of data structures are to be substantially backed up. A request to substantially back up the contents associated with the at least one data structure is executed when it is determined that the contents associated with the at least one data structure are to be substantially backed up. Executing the request allows contents associated with the at least one data structure are substantially backed up in the reserved memory area.

    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： 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.

    摘要： Techniques are presented for sending an application instruction from a hosting digital appliance to a portable medium, where the instruction is structured as one or more units whose size is a first size, or number of bytes. After flushing the contents of a cache, the instruction is written to the cache, where the cache is structured as logical blocks having a size that is a second size that is larger (in terms of number of bytes) than the first size. In writing the instruction (having a command part and, possibly, a data part), the start of the instruction is aligned with one of the logical block boundaries in the cache and the instruction is padded out with dummy data so that it fills an integral number of the cache blocks. When a response from a portable device to an instruction is received at a hosting digital appliance, the cache is similarly flushed prior to receiving the response. The response is then stored to align with a logical block boundary of the cache.

    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.

    摘要： Technology for replacing a first storage unit operatively coupled to a device is provided. Content of the first storage unit is sent to a new storage unit that serves as the replacement of the first storage unit. In one embodiment, the content is first sent to a trusted third-party server and then transferred from the server to the new storage unit. A portion of the content on the new storage unit is adjusted in one embodiment to maintain content security features that were implemented in the first storage unit. The upgrading can be performed under the control of a software entity that is installed on the device. In various embodiments, the first storage unit may be bound to a third storage unit prior to the upgrade process. In such cases, the process can include measures to bind the new storage unit to the third storage unit.
