Original Abstract Submitted
A PMIC controls multiple power supply circuits. Nonvolatile memory supports repeated writing and has multiple pages. A memory control circuit selects one from among the multiple pages of the nonvolatile memory and writes internal data that indicates an internal state of the power supply management circuit to the write target page. The memory control circuit selects an already-erased page as the write target page and writes the internal data to it, and erases pages other than the write target page.
