Space Qualified, Radiation Hardened SDRAM Memory

Space Micro has developed RHBD innovation hardening techniques, HF-Core Memory Controller and “Architecture” Hardening, that in combination with other known industry standard hardening techniques, plus the innovative use of embedded DRAM and ASIC technologies. We propose to apply these techniques to design and manufacture a radiation hardened, dense and high-speed RH-eDRAM memory integrated circuit from commercial technologies. The new design techniques are portable across advanced geometry, CMOS foundries and can be easily re-applied as commercial SDRAM suppliers migrate to smaller geometries and increased memory sizes. In Phase I. Space Micro will demonstrate the new RHBD radiation mitigation techniques, covert the techniques to circuits and radiation test the innovation. Using these results, we will provide a refined design of the RH-eDRAM design to be manufactured in Phase II. The resulting design will meet and exceed Air Force and other satellite radiation and reliability design goals, providing future satellite hardware designers a dense DRAM memory integrated circuit for computing platforms and solid-state mass memories.
