Abstract
A microprocessor of a solid state memory protects the contents of the solid state memory by comparing a sequence of requests for access to physical blocks of the solid state memory with a predetermined sequence of requests to verify the sequence of requests, and by responding to additional requests for access to the physical blocks of the solid state memory to decrypt and transfer requested files stored therein when the sequence of requests equals the predetermined sequence of requests, thereby verifying the sequence of requests. The predetermined sequence of requests is associated with a plurality of virtual files that can be selected, in a particular sequence, to simulate a request for access to physical blocks of the solid state memory, while the predetermined sequence of requests is stored in a configuration file of the solid state memory in correspondence with an identifier of additional protected files.
