Abstract
A BLSA circuit includes a first inverter disposed between a first sensing node and a second inner bit line, a second inverter disposed between a second sensing node and a first inner bit line, a first capacitor disposed between a first bit line and the first sensing node, a second capacitor disposed between a second bit line and the second sensing node, a first offset canceling switch for electrically coupling the first inner bit line with the second sensing node during an offset canceling operation, a second offset canceling switch for electrically coupling the second inner bit line with the first sensing node during the offset canceling operation, a first isolation switch for electrically coupling the first bit line with the first inner bit line, and a second isolation switch for electrically coupling the second bit line with the second inner bit line.
