Abstract
According to one embodiment, a semiconductor storage device includes a flip-flop circuit configured with two stages of inverters composed of TFETs. The flip-flop circuit includes first and second nodes. A first access transistor composed of a TFET is provided between the first node and a first write word-line. A second access transistor composed of a TFET is provided between the second node and a second write word-line. A MOS transistor which has a gate connected to the first node and responds to a voltage impressed on a read word-line to supply a voltage corresponding to a potential at the first node to a read bit-line is included. The first and second access transistors are configured with TFETs connected in a manner that a drain current flows from the first and second nodes to a write bit-line when turned on.
