Abstract
A method and a memory manager for managing data storage in a plurality of types of memories. The types of memories may comprise a primary memory, such as DRAM, and a secondary memory, such as a phase change memory (PCM) or Flash memory, which may have a limited lifetime. The memory manager may be part of an operating system and may manage the memories as part of a unified address space. Characteristics of data to be stored in the memories may be used to select between the primary and secondary memories to store the data and move data between the memories. When the data is to be stored in the secondary memory, health information on the secondary memory and characteristics of the data to be stored may be used to select a location within the secondary memory to store the data.
