Description
まず、図1に基づき、本発明の実施の形態に係る半導体装置を含む半導体パッケージの構成について説明する。図1は、本発明の実施の形態に係る半導体装置を含む半導体パッケージの構成を示す構成図である。
図3に示すように、半導体装置1は、図2の構成の他に、セレクタ30と、セレクタ31と、パワーオンリセット(以下、PORという)回路32と、eFuse端子33とを有して構成されている。
1ビットのリペアブル情報格納部12aと、31ビットのアドレス情報格納部12bとにより構成されている。このeFuseレジスタ12は、揮発性の不良情報保持回路を構成する。eFuseマクロ13の出力のうち、救済が可能であることを示すイネーブル情報を示す“1”がリペアブル情報格納部12aに格納され、FAILしたアドレスのアドレス情報を示す“80”が31ビットのアドレス情報格納部12bに格納される。eFuseレジスタ12は、リペアブル情報格納部12a及びアドレス情報格納部12bに格納された情報をアドレスコントローラ44に出力する。
