This chapter describes how operating systems manage persistent memory as a platform resource and describes the options they provide for applications to use persistent memory. We first compare memory and storage in popular computer architectures and then describe how operating systems have been extended for persistent memory.
Operating System Support for Memory and Storage
Figure 3-1 shows a simplified view of how operating systems manage storage and volatile memory. As shown, the volatile main memory is attached directly to the CPU through a memory bus. The ...
