Abstract
A memory cell array in a static random access memory (SRAM) includes an improved circuit. Memory cells in one row are connected to a ground line. The memory cells in another row are connected to the ground line. Word lines each are connected alternately to the memory cells of two rows column by column. In a read operation, when one of the word lines is activated, a current flows from the memory cell to the two ground lines. Since a total of currents flowing through one ground line is reduced, the rise of potentials of the ground lines is prevented, so that destruction of data can be prevented.
