Summary:A system and method are described for integrating a memory and storage hierarchy including a non-volatile memory tier within a computer system. In one embodiment, PCMS memory devices are used as one tier in the hierarchy, sometimes referred to as "far memory." Higher performance memory devices such as DRAM placed in front of the far memory and are used to mask some of the performance limitations of the far memory. These higher performance memory devices are referred to as "near memory." L'invention porte sur un système et un procédé pour intégrer une hiérarchie de mémoire et de stockage comprenant un niveau mémoire non volatile dans un système informatique. Selon un mode de réalisation, des dispositifs de mémoire PCMS sont utilisés sous la forme d'un niveau dans la hiérarchie, parfois appelés « mémoire lointaine ». Des dispositifs de mémoire à plus haute performance, tels que de la DRAM, sont placés à l'avant de la mémoire lointaine et sont utilisés pour masquer certaines des limitations de performance de la mémoire lointaine. Ces dispositifs de mémoire à plus haute performance sont appelés « mémoire proche ».
