Description
すなわち、従来のソケット実装タイプのメモリモジュールでは、実装用絶縁基板に設けられる接栓端子のピッチが2.54mmあるいは1.27mmで標準化されていたため、ある大きさの基板に設けることができる接栓端子の数に制約があった。言い換えると、必要な接栓端子数を確保しようとすると、基板の外形寸法が接栓端子数によって律速されてしまうという問題点があった。
本発明の前記並びにその他の目的と新規な特徴については、本明細書の記述および添付図面から明らかになるであろう。
すなわち、絶縁基板の表裏に設けられる接栓端子を、互いに電気的に絶縁された別個の接栓端子となるように形成するようにしたものである。
具体的には、互いに対向する第1及び第3の辺と、互いに対向する第2及び第4の辺とを有する矩形状の絶縁基板と、前記第1の辺に沿って前記絶縁基板の表面側及び裏面側に互いに電気的に絶縁されて設けられた複数の接栓端子と、前記絶縁基板に設けられ、複数のメモリと前記複数のメモリに共通信号を伝達するドライバとを含む複数の半導体装置と、前記絶縁基板に設けられ、前記半導体装置と前記接栓端子とを電気的に接続する配線とを備えた半導体実装装置としたものである。
すなわち、ICが実装される絶縁基板に、ピッチを変えることなく従来の2倍の数の接栓端子を設けることができ、あるいは、接栓端子の数が同一ならば絶縁基板の大きさをおよそ半分にすることができる。
絶縁基板10が装着されるソケット40は、前記接栓端子11a,11b,11c………および11a,11b,11c………と11a’,11b’,11c’………の数に対応した端子ピン41a,41b,41c………を外側に有し、内側には上記ノッチ12a,12bに対応した位置にそれぞれ上記ノッチと係合可能な突起42a,42bを有している。
11a,11b,11c 接栓端子
12a,12b メカニカルキーイン用のノッチ
13a,13b 抜け止め用のノッチ
17a〜17d PD端子
20 メモリIC
30 ドライバIC
40 ソケット
50a,50c ジャンパーチップ
Claims (2)
- 互いに対向する第1及び第3の辺と、互いに対向する第2及び第4の辺とを有する矩形状の絶縁基板と、
前記第1の辺に沿って前記絶縁基板の表面側及び裏面側に互いに電気的に絶縁されて設けられた複数の接栓端子と、
前記絶縁基板の表面と裏面にそれぞれ設けられた複数のメモリICと前記複数のメモリICに共通信号を伝達するドライバICとを含む複数の半導体装置と、
前記絶縁基板の前記第1の辺の略中央に設けられた誤挿入防止のためのメカニカルキーイン用ノッチとを備え、
前記絶縁基板の表面に設けられたメモリICと前記絶縁基板の裏面に設けられたメモリICの対応する外部端子同士が、前記絶縁基板に形成された共通の配線パターンを介して前記絶縁基板の表面側または裏面側の接栓端子のいずれか一つの接栓端子に接続されてなることを特徴とするメモリモジュール。 - 前記絶縁基板は、前記第1の辺に設けられた誤挿入防止のためのノッチに加えて、前記第2及び第4の辺にそれぞれ設けられた抜け止め用のノッチとを備えることを特徴とする請求項1記載のメモリモジュール。
