Abstract
An input-output line sense amplifier of a semiconductor memory device that consumes a small amount of current and direct current (DC), includes a current sensing circuit for sensing only a portion of the current through the input-output line and the complementary input-output line, a first amplifier operating from another portion of the sensed current and of the complementary current to amplify and invert a first detected output signal of the current sensing circuit, a second amplifier operating from yet another portion of the sensed current and of the complementary current to amplify and invert a second detected output signal of the current sensing circuit.
