Designing a New Memory Management Unit for Hybrid Memory
With the spread of flash storage, flash as a replace- ment for part of main memory is hot topics for today’s computer system. While having a good random access performance, flash storage is more power efficiency but also having larger memory than DRAM. In this paper, we propose a design of new hybrid memory management system by hardware to assists the hybrid DRAM and flash memory model. It provides LRU page buffer to reduce the page fault interrupt processing, and make efficient object cache on DRAM. To proof of the concept, we will implement new memory management unit to computer system.
