Semiconductor memory device
First Claim
1. A semiconductor memory device comprisinga plurality of memory cells arranged in rows and columns to form a matrix,a first bit line to which memory cells of a first column are connected, each of the memory cells of the first column comprising an N-channel FET and capacitance means,a second bit line to which memory cells of a second column are connected, each of the memory cells of the second column comprising a P-channel FET and capacitance means,the first bit line and the second bit line being connected to complementary terminals of a sense amplifier to form a folded-bit line pair,a word line connected to the gate of the N-channel FET of one of the memory cells of the first column and to the gate of the P-channel FET of one of the memory cells of the second column, andmeans selectively providing the word line with a first voltage to make conductive the N-channel FET connected thereto and to make nonconductive the P-channel FET connected thereto, or a second voltage to make conductive the P-channel FET connected thereto and make nonconductive the N-channel FET connected thereto, or a third voltage to make nonconductive both the N-channel FET and the P-channel FET connected thereto.

Abstract
In a semiconductor memory device, memory cells of a first column each comprising an N-channel FET are connected to a first bit line, and memory cells of a second column each comprising a P-channel FET are connected to a second bit line. The first bit line and the second bit line are connected to complementary terminals of a sense amplifier to form a folded-bit line pair. A work line is connected to the gate of the N-channel FET of one of the memory cells of the first column and to the gate of the P-channel FET of one of the memory cells of the second column. The word line is selectively provided with a first voltage to make conductive the N-channel FET connected thereto and to make nonconductive the P-channel FET connected thereto, or a second voltage to make conductive the P-channel FET connected thereto and to make nonconductive the N-channel FET connected thereto, or a third voltage to make nonconducitve both the N-channel FET and the P-channel FET connected thereto.
