Abstract
A semiconductor memory device includes a memory cell array having a plurality of read word lines, a plurality of first and second read bit lines, and a plurality of memory cells arranged in array. The memory cell includes a first and a second cell node in complementary pair, a first drive transistor controlled by the second cell node, and a second drive transistor controlled by the first cell node. The read word line and the first read bit line are connected with each other via the first drive transistor. The read word line and the second read bit line are connected with each other via the second drive transistor.
