ルネサスの高性能マルチポートメモリのポートフォリオには、非同期型、同期型のデュアルポート、4ポート、バンク切替型デュアルポートなど、100種類以上の製品があります。 当社のマルチポートメモリ製品は、同時アクセス機能を備えており、競合やシステムの待機状態を防ぐために、設計者は多くの仲裁のテクニックを利用できます。 オンチップ・ハードウェア・アービトレーション、セマフォ・トークン・パッシング、ソフトウェアアービトレーションにより、設計者はアプリケーションに最も効率的なマルチポートメモリを選択することができます。

  • マルチポートは、x8、x9、x16、x18、x36、最大x72ビットのバス幅のバスマッチング問題を解決
  • 1.8V、2.5V、3.3V、5VのI/Oに対応したマルチポートにより、電圧の異なる部品を併用することが可能
  • 非同期メモリではDC～10ns、同期デバイスでは最大200MHzのバススピードのミスマッチをマルチポートでバッファリング可能
  • 8Kbから36Mbまでのマルチポート密度により、幅広いアプリケーションに対応可能
