RIMC VHDL IP Core Radiation Hardened DDR3 Solution

RIMC DDR3 is a fully configurable DDR3 SDRAM Radiation Intelligent Memory Controller. This IP core is designed to work with 3D PLUS DDR3 memory modules to achieve a global radiation hardened DDR solution.

By its radiation intelligent A.I, this IP Core prevents the DDR3 memory from:

  • SEFI: No SEFI were observed up to LET > 60 MeV.cm²/mg.
  • SEU/MBU: It mitigates the SEU by using ECCs (Hamming or Reed Solomon) and includes scrubbing mechanisms to correct SEUs and SERE.
