Summary:A storage device includes a drive selection section (1), a hard disc drive (HDD) (2), and a non-volatile memory drive (3). When an instruction such as a data I/O instruction is issued from a host such as a CPU (5) and an ATA controller (6) to the hard disc drive (HDD) (2), the drive selection section (1) receives the address value. If the address value is contained in the address space predefined, the non-volatile memory drive (3) is made to execute the instruction. Otherwise, the hard disc drive (HDD) (2) is made to execute the instruction. L'invention porte sur un dispositif de mémoires comprenant un sélectionneur (1) de mémoire, un disque dur (2) et une mémoire non volatile (3). Lorsqu'un hôte tel qu'une unité centrale ou un contrôleur ATA transmet une instruction d'E/S au disque dur (2), le sélectionneur reçoit la valeur d'adresse. Si cette dernière est contenue dans un espace d'adressage prédéterminé, c'est à la mémoire non volatile (3) d'exécuter l'instruction, sinon, c'est au disque dur (2).
