champsim-ramulator

A simulator integrates ChampSim and Ramulator.

clrdram

Circuit-level model for the Capacity-Latency Reconfigurable DRAM (CLR-DRAM) architecture.

crow

Source code for the architectural and circuit-level simulators used for modeling the CROW

dram-bender

DRAM Bender is the first open source DRAM testing infrastructure that can be used to easily and comprehensively test state-of-the-art DDR4 modules of different form factors. Five prototypes are available on different FPGA boards. Described in our preprint: https://arxiv.org/pdf/2211.05838.pdf

dram-datasheet-survey

A survey of manufacturer-provided DRAM operating parameters and timings as specified by DRAM chip datasheets from between 1970 and 2021. This data and its analysis are described in the 2022 paper by Patel et al.: https://arxiv.org/abs/2204.10378

drampower

Fast and accurate DRAM power and energy estimation tool

dvfs

MSci project on DVFS, energy savings, and scheduling in Assymetric Multicore Processors (AMPs), using the gem5 simulator.

gpgpusim-ramulator

The source code for GPGPUSim+Ramulator simulator. In this version, GPGPUSim uses Ramulator to simulate the DRAM. This simulator is used to produce some of the results in our SIGMETRICS 2019 paper: Ghose et al., "Demystifying Complex Workload-DRAM Interactions: An Experimental Study" at https://arxiv.org/pdf/1902.07609.pdf.

memben

Benchmark suite containing cache filtered traces for use with Ramulator. These include some of the workloads used in our SIGMETRICS 2019 paper: Ghose et al., "Demystifying Complex Workload-DRAM Interactions: An Experimental Study" at https://arxiv.org/pdf/1902.07609.pdf.

mimdram

Source code for the architectural simulator used for modeling the PUD system proposed in our HPCA 2024 paper `MIMDRAM: An End-to-End Processing-Using-DRAM System for High-Throughput, Energy-Efficient and Programmer-Transparent Multiple-Instruction Multiple-Data Processing''. Paper is at: https://arxiv.org/pdf/2402.19080.pdf

ramulator

A Fast and Extensible DRAM Simulator, with built-in support for modeling many different DRAM technologies including DDRx, LPDDRx, GDDRx, WIOx, HBMx, and various academic proposals. Described in the IEEE CAL 2015 paper by Kim et al. at http://users.ece.cmu.edu/~omutlu/pub/ramulator_dram_simulator-ieee-cal15.pdf

ramulator-pim

A fast and flexible simulation infrastructure for exploring general-purpose processing-in-memory (PIM) architectures. Ramulator-PIM combines a widely-used simulator for out-of-order and in-order processors (ZSim) with Ramulator, a DRAM simulator with memory models for DDRx, LPDDRx, GDDRx, WIOx, HBMx, and HMCx. Ramulator is described in the IEEE CAL

ramulator2

Ramulator 2.0 is a modern, modular, extensible, and fast cycle-accurate DRAM simulator. It provides support for agile implementation and evaluation of new memory system designs (e.g., new DRAM standards, emerging RowHammer mitigation techniques).
