DESTINY: A Tool for Modeling Emerging 3D NVM and eDRAM caches

To drive architecture and system-level studies into 3D ReRAM and other emerging memory technologies, a group of researchers at Oak Ridge National Lab, Penn State and UCSB have developed a modeling tool named DESTINY. DESTINY is an acronym for 3D dEsign-Space exploraTIon tool for SRAM, eDRAM and Non-volatile memorY. It can model both 2D and 3D caches designed with five prominent memory technologies: ReRAM, STT-RAM, PCM, eDRAM and SRAM, at technology nodes ranging from 22nm to 180nm. Thus, DESTINY is a comprehensive tool which can model both conventional and emerging technologies.

DESTINY facilitates design-space exploration across several dimensions, such as optimizing for a target (e.g. latency or area) for a given memory technology, choosing the suitable memory technology or fabrication method (i.e. 2D v/s 3D) for a desired optimization target etc. DESTINY has been validated against several industrial cache prototypes.

The DESTINY code can be downloaded from code.ornl.gov/3d_cache_modeling_tool/destiny

DESTINY should be compiled with a user-specified configuration file ($ ./destiny *.cfg). The output of DESTINY is the area, latency and energy values for the cache. More details can be found in the manual entitled ”DESTINY_Documentation” in folder ‘Doc’ in the git repository. This file shows an example configuration file and the corresponding output of DESTINY, which may be especially useful for a user who wants to get an overview of DESTINY even before installing it.

The following DATE-2015 paper provides a general introduction of DESTINY: Matt Poremba, Sparsh Mittal, Dong Li, Jeffrey S Vetter and Yuan Xie, “DESTINY: A Tool for Modeling Emerging 3D NVM and eDRAM caches”, DATE, 2015.

    Hello Christie
    Greetings.

    Thanks for including DESTINY on ReRAM forum.

    I also wanted to bring to your notice our two survey papers both accepted in IEEE TPDS 2015 which review techniques for NVMs, including ReRAM:

    1. This paper surveys 140 papers on Flash, ReRAM, PCM and STT-RAM for main memory and storage systems.
    A Survey of Software Techniques for Using Non-Volatile Memories for Storage and Main Memory Systems
    (Soon to be published on IEEE Xplore)

    2. This paper surveys 110 papers on ReRAM, PCM and STT-RAM (and eDRAM) for on-chip cache.
    A Survey Of Architectural Approaches for Managing Embedded DRAM and Non-volatile On-chip Caches
    Link on IEEE: http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6816046

    These surveys are very comprehensive. If you like, you may kindly mention them on your website. Thank you very much.

    Thanks and Regards
    Sparsh Mittal

    Hi, This may not be the right place to post this but do you have any idea how to make sense of the csv file produced as output with Destiny3D. Thanks
