PURPOSE:To sufficiently maintain the sensitivity of a sense amplifier even when a memory cell array is formed with high density by forming the sense amplifier in an area of large width. CONSTITUTION:The width of each sense amplifier 2a, 3a is made wider than the width of an area A where two arrays of memory cells 1a are formed at intersections with each word line WL on a pair of bit lines BL. |
