Abstract
EL PROCESO DE EXPLOTACION DE LA MEMORIA EN UN SISTEMA INFORMATICO DEL TIPO DE DIRECCION VIRTUAL ESTA CARACTERIZADO EN QUE: SE ORGANIZA UN PRIMER DOMINIO DE MEMORIA DX ALREDEDOR DE UNA DIRECCION DE DIMENSION NX BITS. SE DEFINE EN EL DOMINIO DE MEMORIA DX UNA PLURALIDAD DE ESPACIOS DE DIRECCION EAX DE ESTRUCTURA IDENTICA Y ADMITIENDO UNA DIRECCION RELATIVA DE DIMENSION NL INFERIOR A NX. SE AFECTA DE MODO TEMPORAL E INTERCAMBIABLE UNO DE LOS ESPACIOS DE DIRECCION EAX (A CONTINUACION LLAMADO ESPACIO DE DIRECCION CORRIENTE EAC) A UN SEGUNDO DOMINIO DE MEMORIA DL ORGANIZADO ALREDEDOR DE UNA DIRECCION DE DIMENSION NL BITS. EL INVENTO CONCIERNE IGUALMENTE UN DISPOSITIVO PARA PONER EN OBRA EL PROCESO DEFINIDO MAS ABAJO.
