Abstract
Subarrays, which constitute a memory cell array, each include a bit line driving transistor having a drain connected to a bit line, a source is connected to an interconnection having a power supply potential, and a gate is connected to a sub-bit line. The plurality of memory cells are each provided in such away that a gate is connected to a word line, a source is grounded, and whether a drain is connected to the sub-bit line or not is selected in correspondence to data to be stored. Transmission transistors each have a gate connected to the bit line, a source connected to a loading transistor section, and a drain connected to the sub-bit line.
