Description
本発明は、以下の特許出願(それら全ては参照により本明細書に組み込まれる)に関連した内容を含むことができる。即ち、(1)発明者Raymond G. Beausoleil、Marco Fiorentino、Norman Paul Jouppi、Qianfan Xu、Robert Samuel Schreiber、及びNathan Lorenzo Binkertによる「PHOTONIC INTERCONNECTS FOR COMPUTER SYSTEM DEVICES」と題する米国特許出願(代理人整理番号第200704210-1号)、及び(2)発明者Moray McLaren、Jung Ho Ahn、Alan Lynn Davis、Nathan Lorenzo Binkert、及びNorman Paul Jouppiによる「THREE- DIMENSIONAL MEMORY MODULE ARCHITECTURES」と題する米国特許出願(代理人整理番号第200703074-1号)。
将来のシリコンベースのコンピュータシステムの成長は根本的に、信号品位、ワイヤベースの広域信号伝送、及び熱的特性の内部に関連した問題により制限される。集積回路の製造技術は徐々に、トランジスタのサイズを縮小し、トランジスタを相互接続するワイヤがますます、制約の問題になっている。
ダイの三次元(3D)スタック(積重体)でパッケージングされたコンピュータシステムが、本発明の様々な実施形態に従って説明される。一実施形態において、コンピュータシステムのパッケージは、電気的ダイ、及び電気的ダイに結合されて電気的ダイと積み重ねられた光学的ダイを含む。電気的ダイは、電気信号を処理して伝えるための回路を含み、光学的ダイは、光信号を伝送するための構造体を含む。電気的ダイは、光学的ダイが光入力/出力ポートを有するように構成された露出したメザニンを含むように、光学的ダイよりも小さい面積を有する。更に、パッケージは、外部光接続の挿入の力に対する構造的支持を提供するように構成され得る。
本発明は、三次元のダイスタックのアーキテクチャ及びパッケージングの技術に関する実施形態を開示する。本明細書で開示された実施形態を使用して、広域相互接続用のワイヤベースの電気信号伝送を光相互接続に有利に置き換えることができる。
図4Aは、本発明の実施形態による、プロセッサダイ102のクラスタ402を示す。クラスタ402は、4つのコアを含む。各コアはL1命令キャッシュ及びL1データキャッシュと電気通信する。L1命令キャッシュ及びL1データキャッシュは、高い頻度で又は最近のアクセスされた命令およびデータを一時的に格納する高速ランダムアクセスメモリである。
