Semiconductor device

A semiconductor device comprising:

• a plurality of memory cells arranged in a matrix and each operable to store data in a nonvolatile manner;
• a plurality of first write current lines arranged corresponding to columns of the memory cells;
• a plurality of second write current lines arranged corresponding to rows of the memory cells;
• a write current adjusting unit operable to adjust a current amount of write current to be flowed through at least one of the first write current lines and the second write current lines, in order to perform data write normally to each of the memory cells;
• a first write circuit electrically coupled to the first write current lines;
• and
• a second write circuit electrically coupled to the second write current lines,
• wherein at least one of the first write circuit and the second write circuit writes data in each of the memory cells, by flowing write current through at least one of the first write current lines and the second write current lines based on the current amount adjusted by the write current adjusting unit, and
• wherein the write current adjusting unit divides at least one of the first write current lines and the second write current lines into units of at least one write current line as division units, and includes a plurality of write current adjusting circuits operable to adjust the current amount of write current in each of the division units concerned.
