DRAMSys: A Flexible DRAM Subsystem Design Space Exploration Framework

Abstract: Abstract:In systems ranging from mobile devices to servers, Dynamic Random Access Memories (DRAM) have a big impact on performance and contributes a significant part of the total consumed power. Conventional DDR3-based solutions are stretched thin as their maximum bandwidth is limited by the I/O count and interface speed. As new solutions are coming onto the market (JEDEC DDR4, JEDEC WIDE I/O, Micron's hybrid memory cube: HMC or JEDEC's high bandwidth memory: HBM) it is critical to evaluate the performance of … Show more

“…There are a few prevailing address mapping schemes, such as Bank Interleaving [22,23], Permutation-Based Page Interleaving [24,25], Bit-Reversal [26]. Apart from these general-purpose address mapping schemes, a few memory controllers employ an address mapping that is tailored for a particular application, for example, the Toggling Rate Analysis presented in [27,28]. These Application-Specific Memory Controllers (ASMC) [29] are designed from the overall system perspective and effectively utilize the application knowledge to largely improve the memory system bandwidth and reduces the DRAM energy in contrast to generalpurpose memory controllers.…”

“…The simulator uses the gem5 7 framework as functional simulator and includes DRAMSys and DRAMPower. 13,16 Thanks to the addition of DRAMSys and DRAMPower, the emulation environment is capable of modeling data retention starting from memory physical parameters and producing at run-time power consumption data. Presented results demonstrate that, for the two cases taken as case study, refresh rate can be completely disabled with a negligible degradation on output quality.…”
