摘要： The quality of data stored in individual blocks of memory cells of a flash memory system is monitored by a scrub read of only a small portion of a block, performed after data are read from less than all of a block in response to a read command from a host or memory controller. The small portion is selected for the scrub read because of its greater vulnerability than other portions of the block to being disturbed as a result of the commanded partial block data read. This then determines, as the result of reading a small amount of data, whether at least some of the data in the block was disturbed by the command data read to a degree that makes it desirable to refresh the data of the block.

摘要： In a nonvolatile memory with block management system, data are written to blocks and are erasable block by block. At any time a pool of blocks are open for storing data concurrently. The number of blocks in the pool is limited. A replacement system allows new blocks to be introduced into the pool without exceeding the limit. In particular, different classes of blocks in the pool each has its own replacement rule, such as closing a least active block before being replaced. In this way, possible inefficiency and premature closure of blocks in the pool can be avoided.
摘要翻译：在具有块管理系统的非易失性存储器中，数据被写入块并且可以逐块擦除。在任何时候，可以同时打开一组块来存储数据。池中的块数量是有限的。替代系统允许在不超出限制的情况下将新块引入池中。特别是，池中不同类别的块都有其自己的替换规则，例如在被替换之前关闭最小活动块。通过这种方式，可以避免池中块的可能无效和过早关闭。

摘要： In a nonvolatile memory system, first raw data is obtained from stored data using a first set of reading parameters. Subsequently, the first raw data is transferred to an ECC circuit where it is decoded. While the first raw data is being transferred and decoded, second raw data is obtained from the same stored data using a second set of reading parameters.

摘要： A method and storage device are disclosed for card-based management of discardable files, where discardable files are tracked in a discardable file system on a storage device and are invisible to a host file system, which only tracks user files and free space. The method includes the storage device detecting currently free logical clusters corresponding to at least a portion of free space in the storage area and determining whether addresses associated with a subsequent user file write request are in a range of free clusters managed in the discardable file system by the storage device. When addresses in a host write request overlap the addresses of space managed by the discardable file system, the storage device discards discardable files as necessary and removes the newly freed clusters from the discardable file system, such that the discardable file system data structure is resized when room for user files is needed.
摘要翻译：公开了一种用于对可丢弃文件进行卡片管理的方法和存储装置，其中可放弃文件在存储装置上的可丢弃文件系统中被跟踪，并且对于仅跟踪用户文件和可用空间的主机文件系统是不可见的。该方法包括：存储设备检测与存储区域中的至少一部分可用空间相对应的当前空闲逻辑簇，并且确定与随后的用户文件写入请求相关联的地址是否在可丢弃文件系统中管理的空闲群集的范围内存储设备。当主机写请求中的地址与可丢弃文件系统管理的空间的地址重叠时，存储设备根据需要丢弃可丢弃的文件，并从可丢弃的文件系统中移除新释放的群集，使得可丢弃的文件系统数据结构在需要用户文件的空间。

In one embodiment, a memory device is provided comprising a memory operative to store content and a controller in communication with the memory. The controller is operative to generate a content protection algorithm that is different from at least one content protection algorithm previously generated by the controller, protect the content in accordance with the content protection algorithm, generate virtual machine code containing instructions on how to unprotect the protected content, and provide the protected content and the virtual machine code to a host in communication with the memory device. In another embodiment, a method for adaptive protection of content is provided comprising generating a content protection algorithm that is different from at least one previously-generated content protection algorithm, protecting content in accordance with the content protection algorithm, generating virtual machine code containing instructions on how to unprotect the protected content, and providing the protected content and the virtual machine code to a host in communication with the memory device.

摘要： Host devices present both the host certificate and the pertinent certificate revocation lists to the memory device for authentication so that the memory device need not obtain the list on its own. Processing of the certificate revocation list and searching for the certificate identification may be performed concurrently by the memory device. The certificate revocation list for authenticating a host device to a memory device is cached and current prior to the memory device receiving the host certificate.
