Abstract: A semiconductor storage device includes a substrate having first, second, third, and fourth lateral sides and a connector interface on the first lateral side, a nonvolatile semiconductor memory disposed on a surface of the substrate between the first lateral side and the second lateral side, which is opposite to the first lateral side, a memory controller disposed on a surface of the substrate between the first lateral side and the second lateral side, and a support for the memory controller disposed on a surface of the substrate to support at least one side of the memory controller.

Abstract: An electronic apparatus includes a housing, a first circuit board including a first engaging portion configured to fix the first circuit board to the housing, and a first terminal, and a second circuit board including a second engaging portion configured to fix the second circuit board to the housing, and a second terminal electrically connected to the first terminal.

Abstract: An electronic device includes a first electronic unit, a second electronic unit disposed adjacent to the first electronic unit, and a heat radiating unit. The second electronic unit has a first portion and a second portion that is closer to the first electronic unit than the first portion. The heat radiating unit is disposed such that heat generated in the second portion of the second electronic unit is directed towards the first portion of the second electronic unit and from the first portion towards an outside of the electronic device.
