| 摘要 |
A memory module of the present invention has a memory core chip for storing information, an interface chip for controlling data input/output, an interposer chip for transmitting/receiving data to/from the outside, and an external connection terminal provided in closest proximity to the interposer chip. A heat dissipating plate is provided in closest proximity to the interface chip. The interposer chip has a substrate made of a semiconductor material that is similar to the memory core chip, a land for holding the external connection terminal, a wire connected to the external connection terminal, and an insulating film for insulating the wire. The land, wire, and insulating film are integrally formed on one surface of the interposer chip.
