Patent ID: 8269325

Claim:
A semiconductor storage device, comprising: an organic board, which is provided with external connection terminals on one surface side and in which internal wiring is formed; a lead frame or a non-conductive supporting board positioned relative to another surface side that is a surface side opposite to the one surface side of the organic board; a semiconductor memory chip provided on a surface side, which is opposite to a surface positioned to the organic board, of the lead frame or the non-conductive supporting board via an adhesive material; a controller chip that is provided on the another surface side via an adhesive material and is configured to control the semiconductor memory chip; a metal wire configured to electrically connect the semiconductor memory chip and the controller chip with the internal wiring; and a resin mold portion covering the semiconductor memory chip, the controller chip, and the metal wire, wherein the resin mold portion seals the another surface side with the one surface side being exposed, and the organic board is formed as an individual piece into a plane shape substantially identical to an area where the external connection terminals are provided.
