As DRAM faces scaling limit, several new memory technologies are considered as candidates for replacing or complementing DRAM main memory. Compared to DRAM, the new memories have two major differences, non-volatility and write overhead in terms of endurance, latency and power. We built two different FPGA-based evaluation boards to evaluate hardware and software designs for new-memory based main memory; one with a DRAM subsystem having parameterizable latency and non-volatility emulation, and the other with the real chips of new memory namely phase-change RAM (PRAM). We experimented primitive functions and SQLite-based benchmarks on Linux, verifying the workings of new functionalities, e.g., nonvolatility and evaluating the impacts of new memory on software performance. In our experiments, we also demonstrated the impact of new memory-aware software/hardware designs on program performance on a DRAM/PRAM hybrid memory.
