Title (EN) ESTIMATION OF NON-LINEAR DISTORTION IN MEMORY DEVICES
(FR) ESTIMATION DE DISTORSION NON LINÉAIRE DANS DES DISPOSITIFS À MÉMOIRE
Abstract:
(EN) A method for operating a memory (24) includes storing data in analog memory cells (32) of the memory by writing respective analog values to the analog memory cells. Identifying an interfered cell having a distortion that is statistically correlated with the respective analog values of the analog memory cells in a set of the analog memory cells. Determining a mapping between combinations of possible analog values of the analog memory cells in the set and statistical characteristics of composite distortion levels present in the interfered memory cell. The mapping is applied to compensate for the distortion in the interfered memory cell.
(FR) L'invention concerne un procédé d'exploitation d'une mémoire (24) consistant à stocker des données dans des cellules de mémoire analogique (32) de la mémoire par écriture de valeurs analogiques respectives dans les cellules de mémoire analogique. Un ensemble de cellules de mémoire analogique est identifié, notamment une cellule interférée présentant une distorsion qui est statistiquement corrélée avec les valeurs analogiques respectives des cellules de mémoire analogique de l'ensemble. Un mappage est déterminé entre des combinaisons de valeurs analogiques possibles des cellules de mémoire analogique de l'ensemble et des caractéristiques statistiques de niveaux de distorsion composite présents dans la cellule de mémoire interférée. Le mappage est appliqué de manière à compenser la distorsion de la cellule de mémoire interférée.
