Abstract
To improve the reliability of controlling overwriting of a nonvolatile memory in a data processing semiconductor device. In a data processing semiconductor device, a control unit which controls reading, writing, or erasing of data in a rewritable nonvolatile memory area has an operation mode that, referring to the input temperature data, controls a temperature range in which writing or erasing of data is performed to be narrower than the temperature range that allows reading of data in the memory area.
Claims18
A data processing semiconductor device comprising:
- nonvolatile memory unit having a rewritable nonvolatile memory area;
- and
- a control unit which controls reading, writing, or erasing of data in the memory area,
- wherein the control unit has a first operation mode which, referring to input temperature data, controls a temperature range for writing or erasing data to be narrower than a temperature range that allows reading of data in the memory area.
A data processing semiconductor device comprising:
- a nonvolatile memory unit having a rewritable nonvolatile memory area;
- and
- a control unit which controls reading, writing, or erasing of data in the memory area,
- wherein the control unit has a first operation mode which, referring to input temperature data, controls a temperature range that guarantees writing or erasing of data to be narrower than a temperature range that guarantees reading of data in the memory area.
