Abstract
The bit-line sense amplifier includes a driving-voltage control circuit and an amplifier. The driving-voltage control circuit generates a first test driving voltage having a voltage level of a pre-charge voltage, a second test driving voltage having a voltage level of a pre-charge voltage added by a voltage difference between a bit-line and a complementary bit-line, and a third test driving voltage having a voltage level of a pre-charge voltage subtracted by the voltage difference in a test mode. The amplifier senses and amplifies a voltage difference between the bit-line and the complementary bit-line.
