Data Center RDIMM DDR4 Tester
An experimental platform for development of RAM controllers supporting RDIMM DDR4 RAM modules commonly used in data centers, built around the Xilinx Kintex-7 FPGA.
This hardware platform is used in Antmicro's and Google's Rowhammer testing framework which can be used to perform (and potentially mitigate) Rowhammer-type attacks on DRAM memories. You can learn more about Rowhammer and our work towards mitigating it in a Google Open Source blog note describing a related platform. You can read more about this board in this Antmicro blog note.
