A memory cell array includes memory cells disposed in a matrix. A plurality of word-lines are arranged in the memory cell array to select a memory cell in a row direction. A read bit-line pair is arranged in a direction perpendicular to the word-line to read data from the memory cell. In addition, a write bit-line is arranged in a direction perpendicular to the word-line to write data to the memory cell. The read bit-line pair includes a true and a complementary read bit-line. One of the true and complementary read bit-lines is connected to the memory cell connected to an even-numbered word-line. The other one is connected to the memory cell connected to an odd-numbered word-line.
