摘要： A method for re-allocating memory partition space is provided. The method comprises determining when a first memory partition is full or has reached a threshold value, determining that a second memory partition has unused storage space that can be allocated to the first memory partition, and assigning the unused storage space from the second memory partition to the first memory partition. A memory controller embedded within the mass storage device and having an interface to an external host assigns the unused storage space from the second memory partition to the first memory partition.

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： 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： 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.

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.
