Abstract: The present invention is directed to computer storage systems and methods thereof. More specifically, embodiments of the present invention provide an isolated storage control system that includes both a non-volatile memory and a volatile memory. The non-volatile memory comprises a data area and a metadata area. In power failure or similar situations, content of the volatile memory is copied to the data area of the non-volatile memory, and various system parameters are stored at the metadata area. When the system restores its operation, the information at the metadata area is processed, and the content stored at the data area of the non-volatile memory is copied to the volatile memory. There are other embodiments as well.

Abstract: The present invention is directed to computer storage systems and methods thereof. In an embodiment, a memory system comprises a controller module, a nonvolatile memory, and a volatile memory. The controller module operates according to a command and operation table. The command and operation table can be updated to change the way controller module operates. When the command and operation table is updated, the updated table is stored at a predefined location of the nonvolatile memory. There are other embodiments as well.
