Description
図4は、本発明を、図1で説明したようなチップ(DRAMチップ)の2段スタックに適用した第1の実施例を示す。すなわち、図1で説明したように、チップ100はチャンネル0〜3の4つのメモリエリアにそれぞれTSVアレイ部100−0〜100−3を備える。図中左側の2つのTSVアレイ部100−0、100−2はそれぞれ、互いに隣接するメモリエリアの辺縁に沿って配置され、図中右側の2つのTSVアレイ部100−1、100−3もそれぞれ、互いに隣接するメモリエリアの辺縁に沿って配置されている。
第1の実施例の構成の場合、内部バスは256×2 = 512となって図2に示した現在のワイドI/O DRAMと同じであり、かつ、入出力(DQ)回路はSDRAMインターフェースの倍の高速動作のため大きくなるが、回路数は半分で済むので、現在のワイドI/O DRAM以下の面積で済む。
図5は、4枚のチップをスタックする場合に適用される、本発明の第2の実施例を説明するための図である。図5(a)において、第2の実施例では、チップ300におけるチャンネル0〜3の4つのメモリエリアに対応するように、4つのTSVアレイ部300−0〜300−3を十字型に配置している。そして、ここではTSVアレイ部300−0をDRAMに入出力するためのTSVアレイ部とし、残りのTSVアレイ部300−1〜300−3をパススルーのTSVアレイ部とするようにしている。これにより、4つのチャンネルのうちの3つのチャンネルの入出力(DQ)回路を共通化(共有)することで、チップにおける入出力(DQ)回路の数を1つに減らしている。すなわち、図5(a)では、DRAMに入出力するためのTSVアレイ部300−0側にのみ入出力(DQ)回路を設けている。
