Abstract
A current sense amplifier circuit for a semiconductor memory device includes a differential amplifier which senses the signal currents input to first and second input nodes, amplifies the difference between the two signals and outputs the sense-amplified signals to first and second output nodes. A first feedback circuit is connected between the second input node and a current controlling node and has a controlling terminal connected to the first output node. A second feedback circuit is connected between the first input node and the current controlling node and has a controlling terminal connected to the second output node. By feeding back voltages from the counterpart output nodes through the cross-connected feedback circuits, the difference between low level input signals can be efficiently detected and a stable sense-amplified output is obtained.
