Abstract
The present invention provides a volatile memory backup system including an all-solid-state battery. The backup system includes a volatile memory, a nonvolatile memory connected to the volatile memory so as to transfer data therebetween, an all-solid-state battery connected to the volatile memory and the nonvolatile memory, the battery continuously or intermittently supplying a current to the volatile memory during a power failure to retain data in the volatile memory, and a controller connected in parallel with the battery, the controller intermittently supplying a peak current to the volatile memory during the power failure and intermittently transferring divided volumes of data in the volatile memory to the nonvolatile memory by the peak current and a current from the battery temporarily increased in association with the peak current to store the data in the nonvolatile memory, thereby gradually accumulating the data in the volatile memory into the nonvolatile memory.
