Abstract
According to an embodiment, an electronic apparatus includes a printed circuit board including a plurality of devices that include a nonvolatile memory package and a controller package configured to control the nonvolatile memory package, and a housing accommodating the printed circuit board. The housing includes an opening on a surface constituting the housing. An encryption device among the plurality of devices is present in a first region. The first region is a region on the printed circuit board that is not irradiated with light emitted from a light source placed at the opening. The encryption device is a device used for an encryption process of data to be stored into the nonvolatile memory package.
Claims20
A memory system comprising:
- a first printed circuit board having a first main surface and a second main surface, the second main surface opposing the first main surface;
- a nonvolatile memory;
- a first encryption device mounted on the first main surface, the first encryption device being configured to encrypt data to be stored in the nonvolatile memory;
- and
- a housing including a wall and a first plate, the wall being perpendicular to the first plate, the first plate being parallel to the first printed circuit board, the housing accommodating the first printed circuit board, the nonvolatile memory, and the first encryption device,
- the wall including a first region and a second region, the first region including an opening, the second region including no opening,
- the first plate having a first surface, the first surface facing the first main surface of the first printed circuit board,
- wherein
- the second region of the wall is bounded by a first position and a second position,
- the first position being a position where the wall is intersected by an imaginary extension of the first main surface of the first printed circuit board, and
- the second position being a position where the wall is intersected by an imaginary extension of the first surface of the first plate.
A memory system comprising:
- a first printed circuit board having a first main surface and a second main surface, the second main surface opposing the first main surface;
- a second printed circuit board having a third main surface and a fourth main surface, the fourth main surface opposing the third main surface, the third main surface facing the second main surface of the first printed circuit board;
- a spacer interposed between the first printed circuit board and the second printed circuit board, the spacer including a first part and a second part, a gap between the first part and the second part forming a first slit;
- a nonvolatile memory;
- an encryption device mounted on the second main surface of the first printed circuit board, the encryption device being configured to encrypt data to be stored in the nonvolatile memory;
- and
- a housing including a first wall, the first wall being perpendicular to the first printed circuit board and the second printed circuit board, the housing accommodating the first printed circuit board, the second printed circuit board, the spacer, the nonvolatile memory, and the encryption device,
- the first wall including at least one first opening,
- wherein
- the first part of the spacer and the second part of the spacer locate between the first opening and the encryption device, and
- the first part of the spacer or the second part of the spacer is placed such that the first part of the spacer or the second part of the spacer blocks light emitted from a light source not to irradiate the encryption device if the light source is placed at the first opening.
