    Abstract: 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.

    Abstract: Methods and apparatus for facilitating multi-page or multi-block operations within a non-volatile memory system. According to one aspect of the present invention, a method for performing a multi-page command includes obtaining a first page number of a first convention that identifies a first page associated with a non-volatile memory, and mapping the first page number to a second page number of a second convention. Like the first page number, the second page number also identifies the first page. Mapping the first page number to the second page number includes identifying a total number of districts associated with the non-volatile memory and a total number of pages associated with each block of a total number of blocks. Finally, the first page is accessed using the second page number and the multi-page command.

    Abstract: Methods and apparatus for determining which of a plurality of physical blocks associated with a logical block is more recently associated with the logical block are disclosed. According to one aspect of the present invention, a method for resolving associations of a first physical block and a second physical block to a logical block associated with a non-volatile memory system includes obtaining a first identifier associated with the first physical block and obtaining a second identifier associated with the second physical block. The identifiers are compared to ascertain whether the first identifier indicates that the first physical block is more recently associated with the logical block. The method also includes completing an operation arranged to provide contents associated with the logical block to the first physical block when it is determined that the first identifier indicates that the first physical block is more newly associated with the logical block.
