Abstract:
This disclosure concerns a semiconductor storage device including a bit line; a first capacitor supplying a charge to a cell; a first sense node transmitting a potential corresponding to data of the cell; a first pre-charge part charging the bit line, the first capacitor, and the first sense node; a first latch part latching the data; a first sense part including a first sense transistor connected between a power supply and the first latch part, the gate is connected to the first sense node; and a first clamp part connecting a first node between the first latch part and the first sense transistor to the bit line, wherein the first capacitor supplies the charge to the bit line during detecting, and the first sense part supplies a charge from the power supply to the bit line via the first clamp part in response a potential at the first sense node.
