  • Patent number: 10714853
    Abstract: According to one embodiment, a semiconductor storage device includes a housing, a plurality of terminals, signal terminals, a controller, signal wiring, and a memory. The housing has a first face and a second face opposite to the first face. The plurality of terminals is exposed to the first face, extends in a first direction, and is spaced apart in a second direction intersecting with the first direction. A signal terminal included in the plurality of terminals has a first end in the first direction, and a second end opposite to the first end in the first direction, the second end being closer to a contact position with a socket contact than the first end. The controller is located in the housing. The signal wiring extends from the first end in the housing and electrically connects the first end and the controller. The memory is electrically connected to the controller in the housing.
