Title (EN) SEMICONDUCTOR DIE WITH DIFFERENT MAGNETIC TUNNEL JUNCTIONS IN DIFFERENT MAGNETO-RESISTIVE RANDOM ACCESS MEMORY ARRAYS
(FR) PUCE SEMI-CONDUCTRICE AYANT DES JONCTIONS À EFFET TUNNEL MAGNÉTIQUES DIFFÉRENTES DANS DES RÉSEAUX DE MÉMOIRE VIVE MAGNÉTO-RÉSISTIVE DIFFÉRENTS
Abstract:
(EN) The energy barrier of a magnetic tunnel junction (MTJ) affects its write performance as the amount of current required to switch the magnetic orientation of a free layer of the MTJ is a function of its energy barrier. Thus, by varying the energy barriers of MTJ stacks (204) in different magneto-resistive random access memory (MRAM) arrays (208) in a semiconductor die (200), different MRAM arrays may be used for different types of memory provided in the semiconductor die while still achieving distinct performance specifications. The energy barriers can be varied by varying the materials, heights, widths, and/or other characteristics of the MTJ stacks.
(FR) Dans la présente invention, la barrière énergétique d'une jonction à effet tunnel magnétique (MTJ) a une incidence sur sa performance d'écriture étant donné que la quantité de courant nécessaire à la commutation de l'orientation magnétique d'une couche libre de la MTJ dépend de sa barrière énergétique. Ainsi, par variation des barrières énergétiques d'empilements MTJ (204) dans des réseaux de mémoire vive magnéto-résistive (MRAM) (208) différents dans une puce semi-conductrice (200), des réseaux de MRAM différents peuvent être utilisés pour des types de mémoire différents compris dans la puce semi-conductrice tout en assurant des spécifications de performance distinctes. On peut faire varier les barrières énergétiques par variation des matériaux, des hauteurs, des largeurs et/ou d'autres caractéristiques des empilements MTJ.
