1. A nonvolatile memory system comprising:

  • a nonvolatile memory for storage 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
