Abstract
The present invention provides a semiconductor device including a nonvolatile memory of which the memory size of a data area and the memory size of a code area can be freely changed. The semiconductor device according to one embodiment includes a nonvolatile memory which can switch between a reference current reading system which performs data read by comparing a current flowing through a first memory cell as a read target and the reference current and a complementary reading system which performs data read by comparing currents flowing through a first memory cell and a second memory cell storing complementary data, as a read target.
