Abstract:
Regular chip packages that store user data therein and error-correction chip packages that store an error correction code therein are mounted on a module substrate. The module substrate has first and second mounting areas of different coordinates in an X direction, and the second mounting area has third and fourth mounting areas of different Y coordinates. The regular packages are oppositely arranged in the first mounting area on a surface and the back surface of the module substrate. The error-correction chip packages are oppositely arranged in the third mounting area on the surface and the back surface of the module substrate. A memory buffer that buffers user data and an error correction code is arranged in the fourth mounting area.
Abstract:
Disclosed herein is a semiconductor module that includes a module substrate and a plurality of semiconductor devices mounted on the module substrate. Among the semiconductor devices, two of the semiconductor devices adjacent in a first direction differ in a mounting direction by 180°. Among the semiconductor devices, two of the semiconductor devices adjacent in a second direction perpendicular to the first direction differing in a mounting direction by 180°.
Abstract:
A semiconductor module includes a plurality of rectangular shaped semiconductor devices which are arranged in two rows such that each pair of adjacent semiconductor devices is in orientations differed by 90 degrees from each other. A plurality of wirings connect the semiconductor devices included in one of the two rows to the semiconductor devices included in the other row such that the semiconductor devices arranged in the same orientations are connected to each other.
