DRAMSim2: DRAMSim2 (A cycle accurate DRAM simulator) DRAMSim2: DRAMSim2: DRAMSim2: DRAMSim2 is a cycle accurate model of a DRAM memory controller, the DRAMSim2: DRAM modules which comprise system storage, and the bus by which they DRAMSim2: communicate. All major components in a modern memory system are DRAMSim2: modeled as their own respective objects within the source, including: DRAMSim2: ranks, banks, command queue, the memory controller, etc. DRAMSim2: DRAMSim2: DRAMSim2:
