Abstract
A data transfer circuit includes: a first power domain; a nonvolatile memory configured to store first data; a holding circuit; a readout circuit configured to read the first data from the nonvolatile memory and write the first data into the holding circuit at a time of chip reset; and a first controller configured to transfer the first data written into the holding circuit to the first power domain and make the holding circuit keep the first data at the time of chip reset, wherein the readout circuit, at a time of reset of the first power domain after the chip reset, does not read the first data from the nonvolatile memory, and the first controller transfers the first data held in the holding circuit to the first power domain.
