Abstract
【解決手段】半導体記憶装置10は、一方の面に外部接続端子19が設けられた有機基板11と、半導体メモリチップ15とを備えて、外部機器に挿入可能とされる。半導体メモリチップが載置される載置部21、および載置部から外部機器への挿入方向側に向けて延びるように形成されるとともに有機基板の他方の面に接着される接着部22を有するリードフレーム13と、樹脂モールド部18と、をさらに備える。有機基板は、平面視において載置部とほとんど重ならない形状に個片化されている。接着部挿入方向における端部は、樹脂モールド部内に形成される。リードフレームは、接着部において、樹脂モールド部の挿入方向側の面とは異なる面まで延びる第1延出部13bをさらに有する。
【選択図】図3
Description
図1は、第1の実施の形態にかかる半導体記憶装置の外観を示す平面図である。図2は、図1に示す半導体記憶装置の外観を示す底面図である。図3は、図1に示す半導体記憶装置の内部構成を模式的に示す図である。図4は、図1に示す半導体記憶装置のA−A線に沿った断面構造を示す横断面図である。半導体記憶装置10は、パーソナルコンンピュータやデジタルカメラなどの外部機器に設けられたソケットに挿入されて用いられる。半導体記憶装置10は、外部記憶装置として機能する。なお、半導体記憶装置10の挿入方向は、矢印Xで図示する方向とする。
