Abstract: front page image
(EN)A nonvolatile memory cell (10a, 10b) which is highly scalable includes a cell formed in a triple well (44, 46). A pair of sources (32, 34) for a pair of cells on adjacent word lines (36) each acts as the emitter of a lateral bipolar transistor (68). The lateral bipolar transistor (68) of one cell (10) operates as a charge injector for the other cell (10). The charge injector provides carriers for substrate hot carrier injection onto a floating gate (28b).
(FR)La présente invention concerne une cellule de mémoire non volatile (10a, 10b), hautement évolutive, comprenant une cellule formée dans un puits triple (44, 46). Chaque paire de sources (32, 34), pour une paire de cellules sur des lignes mot adjacentes (36), agit comme émetteur d'un transistor bipolaire latéral (68). Le transistor bipolaire latéral (68) d'une cellule (10) fonctionne comme injecteur de charge pour l'autre cellule (10). L'injecteur de charge fournit des porteurs destinés à injecter des porteurs chauds de substrat sur une grille flottante (28b).
