Description
データ記憶装置は、概して、高速かつ効率的な方法でデータを記憶および読出すように動作する。ある記憶装置は、ソリッドステートメモリセルのアレイを利用して、データの個別ビットを記憶する。そのようなメモリセルは、揮発性(たとえば、DRAM,SRAM)または不揮発性(RRAM(登録商標),STRAM,フラッシュなど)であり得る。
本発明のさまざまな実施形態は、不揮発性メモリセルにアクセスするための半導体装置に向けられる。
図1は、本発明のさまざまな実施形態に従って構築されかつ動作されるデータ記憶装置100の機能ブロック図を提供する。装置100の上位制御は、適当なコントローラ102によって実行され、コントローラ102はプログラム可能であってもよいし、ハードウェアベースのマイクロコントローラであってもよい。コントローラ102は、コントローラインターフェース(I/F)回路104を介して、ホスト装置と通信する。メモリ空間は、(アレイ0〜アレイNで示される)多くのメモリアレイ108を含むように106に示されるが、必要に応じて単一のアレイが利用可能であることが理解されるであろう。各アレイ108は、選択された記憶容量の半導体メモリのブロックを含む。コントローラ102とメモリ空間106との間の通信は、I/F104を介して行なわれる。
