Research into the optimal utilization of magnetic materials in plated wire memories

Description

Plated wire memories are particularly sensitive to two kinds of perturbations because of the absence of material separation between neighbouring memory points along a plated wire. During the read process, it is difficult to localize the magnetization rotation. Therefore we studied the field and the magnetization distribution, and computed the gathered flux. We propose new high density structures from our computer program results. During the write process, the written domain spreads during multiple writings. This may lead to the destruction of the information previously recorded in the neighbouring cells. Two processes have been proposed to avoid this drawback. (author)

Abstract (French)

L'absence de separation materielle entre les points-memoires voisins le long d'un fil magnetique rend ce type de memoire particulierement sensible a deux sortes de perturbations. En lecture, la difficulte de localiser la rotation de l'aimantation nous a conduit a etudier la repartition du champ et de l'aimantation, et a calculer le flux recueilli. En application des programmes de simulation que nous avons ainsi mis au point, nous proposons de nouvelles structures a haute densite. En ecriture, l'elargissement d'une zone inscrite sous l'effet d'ecritures repetees peut conduire a la destruction de l'information enregistree dans les points-memoires voisins. Nous proposons et nous etudions deux procedes pour pallier cet inconvenient. (auteur)
