Abstract

 本発明のメモリ制御装置は、マスタから発行された前記メモリアクセス要求を、メモリデバイス毎のアクセスコマンドに分割するコマンド生成部(102)と、前記複数のメモリデバイスにアクセスコマンドを発行するコマンド発行部(104)、(105)と、マスタ(200)とメモリ(0)、(1)間でデータを必要に応じて入れ換えるデータ制御部(106)とを備え、コマンド生成部(102)は、分割した複数のアクセスコマンドに対応する前記複数のメモリデバイスの物理アドレスが同じ場合と異なる場合とで、複数のメモリデバイスへ同じ物理アドレスを出力する制御と、異なる物理アドレスを出力する制御とを切り替える。
