  • Patent number: 8514636
    Abstract: According to one embodiment, a semiconductor storage device includes a cell array, an even line, an odd line, and sense amplifiers. The cell array includes memory cells holding data. The even line connects to the memory cells. The odd line connects to the memory cells. The memory cells connect to an odd column or the even column. Each the sense amplifiers selectively connect to the odd line or the even line. Each the sense amplifiers includes a latch circuit, a first transistor, a second transistor, and a third transistor. The latch circuit includes a first node and a second node, and holds the data supplied to the first node. The first transistor supplies read data to the latch circuit. The second transistor transfers the data held by the latch circuit to the wiring. The third transistor transfers the data held by the latch circuit to the wiring.
