Embodiment Construction

[0037]An example memory system in which the various aspects of the present invention may be implemented is illustrated by the block diagram of FIG. 1. As shown in FIG. 1, the memory system 10 includes a central processing unit (CPU) 12, a buffer management unit (BMU) 14, a host interface module (HIM) 16 and a flash interface module (FIM) 18, a flash memory 20 and a peripheral access module (PAM) 22. Memory system 10 communicates with a host device 24 through a host interface bus 26 and port 26a. The flash memory 20 which may be of the NAND type, provides data storage for the host device 24. The software code for CPU 12 may also be stored in flash memory 20. FIM 18 connects to the flash memory 20 through a flash interface bus 28 and port 28a. HIM 16 is suitable for connection to a host system like a digital camera, personal computer, personal digital assistants (PDA), digital media players, MP-3 players, cellular telephones or other digital devices. The peripheral access module 22 se...

Abstract

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. All of the content that the user wishes to access 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.
