A data recording system of a semiconductor integrated circuit device having a memory area is disclosed. The semiconductor integrated circuit device is equipped with a memory area that includes a binary area and a multi-level area. The semiconductor integrated circuit device records, in the binary area, data transmitted from a host device as binary data. Further, when no access is provided from the host device, the semiconductor integrated circuit device copies, to the multi-level area, the data recorded in the binary area as multi-level data.
