摘要： Methods and apparatus for performing wear leveling in a non-volatile memory system are disclosed. According to one aspect of the present invention, a method for processing elements included in a non-volatile memory of a memory system includes obtaining erase counts associated with a plurality of erased elements. Each element included in the plurality of elements has an associated erase count that indicates a number of times the element has been erased. The method also includes grouping a number of erased elements included in the plurality of elements into a first set, and storing the erase counts associated with the first set in a memory component of the memory system. Grouping the number of elements into the first set typically includes selecting erased elements included in the plurality of elements which have the highest associated erase counts of the erase counts associated with the plurality of elements.

摘要： A first storage unit is bound to a second storage unit based on a binding type associated with content on the first storage unit, the first storage unit being operated through a first host device, and the second storage unit being operated through a second host device. When content on the first storage unit is requested in the first host device, the first host device will calculate an account identifier based on the binding type associated with the requested content and send the account identifier to a server. The server will send the account identifier to the second host device, and the second storage unit will use the account identifier to calculate a credential. The credential will be sent to the first host device through the server. The credential can be used to access the requested content if the credential is valid.

摘要： In some applications, it may be more convenient to the user to be able to log in the memory system using one application, and then be able to use different applications to access protected content without having to log in again. In such event, all of the content that the user wishes to access in this manner may be associated with a first account, so that all such content can be accessed via different applications (e.g. music player, email, cellular communication etc.) without having to log in multiple times. Then a different set of authentication information may then be used for logging in to access protected content that is in an account different from the first account, even where the different accounts are for the same user or entity.

摘要： A tree structure stored in the storage medium provides control over what an entity can do even after gaining access. Each of the nodes of the tree specifies permissions by an entity who has gained entry through such node of the tree. Some trees have different levels, where the permission or permissions at a node of the tree has a predetermined relationship to permission or permissions at another node at a higher or lower or the same level in the same tree. By requiring entities to comply with the permissions so specified at each of the nodes, the tree feature of this application allows a content owner to control which entities can take action, and which actions each of the entities can take, irrespective of whether the tree has different levels. To enhance the commercial value that can be provided by the mobile storage medium, it is desirable for mobile storage devices to be capable of supporting more than one application simultaneously. When two or more applications are accessing the mobile storage device at the same time, it can be important to be able to separate the operations of the two or more applications so that they do not interfere with one another in a phenomena referred to herein as crosstalk. Two or more preferably hierarchical trees control access to the memory. Each tree comprises nodes at different levels for controlling access to data by a corresponding set of entities where a node of each tree specifies permission or permissions of the corresponding entity or entities for accessing memory data. The permission or permissions at a node of each of the trees has a predetermined relationship to permission or permissions at another node at a higher or lower level in the same tree. Preferably, there is no crosstalk between at least two of the trees.

摘要： The owner of proprietor interest is in a better position to control access to the encrypted content in the medium if the encryption-decryption key is stored in the medium itself and substantially inaccessible to external devices. Only those host devices with the proper credentials are able to access the key. An access policy may be stored which grants different permissions (e.g. to different authorized entities) for accessing data stored in the medium. A system incorporating a combination of the two above features is particularly advantageous. On the one hand, the content owner or proprietor has the ability to control access to the content by using keys that are substantially inaccessible to external devices and at the same time has the ability to grant different permissions for accessing content in the medium. Thus, even where external devices gain access, their access may still be subject to the different permissions set by the content owner or proprietor recorded in the storage medium. When implemented in a flash memory, the above features result in a particularly useful medium for content protection. Many storage devices are not aware of file systems while many computer host devices read and write data in the form of files. The host device provides a key reference or ID, while the memory system generates a key value in response which is associated with the key ID, which is used as the handle through which the memory retains complete and exclusive control over the generation and use of the key value for cryptographic processes, while the host retains control of files.

摘要： In some mobile storage devices, content protection is afforded by dividing the memory into separate areas where access to protected areas requires prior authentication. While such feature does provide some protection, it does not protect against a user who obtained a password by illicit means. Thus, another aspect of the invention is based on the recognition that a mechanism or structure may be provided to divide a memory into partitions and so that at least some data in the partitions can be encrypted with a key, so that in addition to authentication that is required for accessing some of the partitions, access to one or more keys may be required to decrypt the encrypted data in such partitions. In some applications, it may be more convenient to the user to be able to log in the memory system using one application, and then be able to use different applications to access protected content without having to log in again. In such event, all of the content that the user wishes to access in this manner may be associated with a first account, so that all such content can be accessed via different applications (e.g. music player, email, cellular communication etc.) without having to log in multiple times. Then a different set of authentication information may then be used for logging in to access protected content that is in an account different from the first account, even where the different accounts are for the same user or entity.

摘要： The mobile storage device may be provided with a system agent that is able to create at least one hierarchical tree comprising nodes at different levels for controlling access to data stored in the memory by corresponding entities. Each node of the tree specifies permission or permissions of a corresponding entity or entities for accessing memory data. The permission or permissions at the node of each of the trees has, a predetermined relationship to permission or permissions at nodes at a higher or lower or the same level in the same tree. Thus, the mobile storage devices may be issued without any trees already created so that the purchaser of the devices has a free hand in creating hierarchical trees adapted to the applications the purchaser has in mind. Alternatively, the mobile storage devices may also be issued with the trees already created so that a purchaser does not have to go through the trouble of creating the trees. In both situations, preferably certain functionalities of the trees can become fixed after the devices are made so that they cannot be further changed or altered. This provides greater control over access to the content in the device by the content owner. Thus, in one embodiment, the system agent can preferably be disabled so that no additional trees can be created.
