Title (EN) PHASE CHANGE MEMORY
(FR) MÉMOIRE À CHANGEMENT DE PHASE
Abstract: front page image
(EN) The present disclosure includes devices and methods for operating phase change memory cells. One or more embodiments include applying a programming signal to a phase change material of a memory cell, and decreasing a magnitude of a trailing portion of the applied programming signal successively according to a number of particular decrements. The magnitude and the duration of the number of particular decrements correspond to particular programmed values.
(FR) La présente invention concerne des dispositifs et des procédés d’utilisation de cellules de mémoire à changement de phase. Un ou plusieurs modes de réalisation comprennent l’application d’un signal de programmation à un matériel à changement de phase d’une cellule de mémoire et la diminution successive d’une amplitude d’une portion arrière du signal de programmation appliqué conformément à un nombre donné de décréments. L’amplitude et la durée du nombre donné de décréments correspondent aux valeurs particulières programmées.
