Description
図1は、第1の実施形態に従ったMARMの構成を示すブロック図である。メモリセルアレイ11内には、複数のメモリセルMCがマトリクス状に二次元配置されている。各メモリセルMCは、MTJ素子およびセルトランジスタを含む。MTJ素子は、抵抗状態の変化によってデータを記憶し、電流によってデータを書き換え可能な磁気トンネル接合素子である。セルトランジスタは、MTJ素子に対応して設けられ、該対応するMTJ素子に電流を流すときに導通状態となるように構成されている。
図7は、第2の実施形態によるMRAMの平面レイアウト図である。図8は、図7の8−8線(アクティブエリアAA)に沿った断面図である。図9は、図7の9−9線(ロウ方向)に沿った断面図である。
