ABSTRACT:
A semiconductor memory device including a pair of bit lines, a memory cell provided between the pair of bit lines, and a potential difference control device connected to the pair of bit lines. The bit lines include a potential difference therebetween when information stored in the memory cell is read out. The potential difference control device has a transistor control for receiving a first control signal and for responding thereto; thereby, increasing the potential difference between the pair of bit lines up to a predetermined level so as to provide a high speed read-operation and to reliably discriminate a "good" or a "no good" reading when subjected to a screening test.
