BIT-LINE SENSE AMPLIFIER CAPABLE OF COMPENSATING MISMATCH BETWEEN TRANSISTORS, AND SEMICONDUCTOR MEMORY DEVICE INCLUDING THE SAME

摘要

Disclosed is a bit-line sense amplifier enabling the compensation of mismatch between transistors. The bit-line sense amplifier may comprise a pull-up driving circuit, a pull-down driving circuit, and a latch-type sense amplifier. The pull-up driving circuit generates a first driving current which changes in response to an up control signal and provides the same to a first driving power supply line. The pull-down driving circuit generates a second driving current which changes in response to a down control signal and provides the same to a second driving power supply line. The latch-type sense amplifier is connected to the first driving power supply line and the second driving power supply line, and senses a voltage difference between a bit line and a complementary bit line and amplifies the voltage.
