Title
(EN) NON-VOLATILE MEMORY DEVICE
(FR) DISPOSITIF DE MÉMOIRE NON VOLATILE
(JA) 不揮発性記憶装置
Abstract
(EN)
This non-volatile memory device comprises: a memory unit that stores data in a non-volatile manner; a power supply unit that generates an internal voltage and supplies the internal voltage to the memory unit; a control unit that controls the memory unit and the power supply unit; an A/D converter that subjects the internal voltage to A/D conversion; and an abnormality detection unit that detects, on the basis of an output of the A/D converter, an abnormality related to data written to the memory unit.
(FR)
L'invention concerne un dispositif de mémoire non volatile qui comprend : une unité de mémoire qui stocke des données de manière non volatile ; une unité d'alimentation électrique qui génère une tension interne et fournit la tension interne à l'unité de mémoire ; une unité de commande qui commande l'unité de mémoire et l'unité d'alimentation électrique ; un convertisseur A/N qui soumet la tension interne à une conversion A/N ; et une unité de détection d'anomalie qui détecte, sur la base d'une sortie du convertisseur A/N, une anomalie relative à des données écrites dans l'unité de mémoire.
(JA)
不揮発性記憶装置は、データを不揮発的に記憶するメモリ部と、内部電圧を生成して前記内部電圧を前記メモリ部に供給する電源部と、前記メモリ部及び前記電源部を制御する制御部と、前記内部電圧をAD変換するAD変換器と、前記メモリ部に書き込まれているデータに関する異常を前記AD変換器の出力に基づき検出する異常検出部と、を備える。
