ABSTRACT:
A semiconductor memory device includes a plurality of memory cells arranged in rows and columns, a plurality of bit lines, each coupled to the memory cells forming one column, and a MOS transistor connected between a power supply terminal and one end of every bit line. The device further includes at least one test memory cell coupled in series with the MOS transistor, thus forming a series circuit connected between the power supply terminal and the ground.
