Abstract
【解決手段】メモリアレイのためのダイは、少なくとも1つの窒化物読取り専用メモリ(NROM)アレイに、フラッシュビットおよびEEPROMビットを記憶することができる。各アレイは、フラッシュタイプ、EEPROMタイプまたはその両方のタイプのビットを記憶することができる。
【選択図】図2A
Description
図5Bは、2つの物理セクタ130Aおよび130Bを示したもので、物理セクタ130Aは、X本のワード線WLを有するフラッシュ物理セクタであり、物理セクタ130Bは、Y本のワード線WLを有するEEPROM物理セクタである。この2つのタイプの物理セクタは、動作モードが異なっているだけで、基本的に同じ物理セクタである。
最後に、ブロックのすべてのフラッシュ記憶領域がまとめて消去される。そのために、ブロックの共通線CLが消去電圧Veにドライブされ、ブロックのすべてのビット線BLがフローティングに設定され、かつ、ブロックのワード線WLが消去電圧にドライブされる。例えば−7Vの消去電圧が使用される。正の消去電圧を利用することも可能である。
