ABSTRACT:
A memory cell array includes a memory cell region composed of memory cells and a sample cell region composed of word line sample cells and bit line sample cells. The word line sample cell and the bit line sample cell are formed so that by a voltage applied to word lines and bit lines, charge transfer from the floating gate electrode occurs more easily than the memory cell.
