ABSTRACT:
A data control system includes an external memory unit for storing data, a volatile memory for storing at-least-once accessed data from the external memory unit, a nonvolatile memory for storing frequently-accessed pieces of data among the data stored in the volatile memory, and a memory control unit for controlling the external memory unit and the nonvolatile memory. The frequently-accessed data is stored in the nonvolatile memory, so that when the system is powered down, the nonvolatile memory does not lose the frequently-accessed data. When the power is on, the frequently-accessed data can be again accessed rapidly.
