1. A nonvolatile memory system comprising: a nonvolatile memory for storage of digital information arranged in multiple blocks for access; a volatile random access memory for read and write operations coupled to said nonvolatile memory; wherein the volatile random access memory and nonvolatile memory are controlled by one or more controllers; wherein the nonvolatile memory system is coupled to a central processing unit; wherein each block of the nonvolatile memory for storage has one or more pages of stored data accessible through the coupled volatile random access memory; and wherein each page of a block is adapted to be substituted on the fly for any other page of a different block through address mapping; wherein the one or more controllers control the volatile and nonvolatile memories to: perform a read operation on the portion of the digital information to be read and retrieving and storing such from the given block at the associated addressable location, perform a read operation from the volatile memory of any portion or all of the stored digital information in the volatile memory, perform a write operation on any portion of the accessed read digital information from the volatile memory back to the same physical location in the volatile memory for storage therein, and write the digital information stored in the volatile memory back to the nonvolatile memory at a different physical location with the same associated address from which it was read.
