NASA applications range from science missions, space station, earth sensing missions e.g. (EOS), and deep space missions. NASA programs/missions that will benefit include new lunar landers and orbiters, Mars missions (MAVEN), solar system exploration e.g. (Titan, Juno, Europa, comet nucleus return, New Discovery, and Living with a Star (LWS). NASA programs which may continue to be funded by Congress include the Next generation heavy launch vehicle being developed out of NASA MSFC called SLS, the Orion Multipurpose Crew Exploration Vehicle (CEV), Commercial Crew Development Vehicle (CCDev2) and Commercial Orbiter Transportation Service (COTS) would benefit. Memory IC products evolving from this SBIR , and marketed by Space Micro, would have been enabling for NASA programs such as RBSP, GRAIL, LADEE, IRIS, Dawn, SDO, Aquarius, Kepler, Ocean Vector Winds, and space interferometry (SIR). New missions which hopefully will be funded include BARREL, CLARREO, GEMS, solar orbiter, solar probe plus, and ILN. Space Micro would be using these new memory devices in our next generation space communications SDR hardware such as that flown on the NASA GSFC IRIS program and the NASA Ames LADEE program, if the devices were qualified and available today.
This cross cutting technology and evolving Space Micro memory products will also benefit many commercial space platforms, both LEO and GEO telecommunication satellites, including Intelsat, Direct TV, XM radio, Orbcomm, and Iridium Next telecom constellation replenishment, plus standard industry busses including Lockheed's A2100, and Boeing's HS-702. Civil earth sensing applications such as weather/metrology applications e.g. (NOAA GOES and Landsat) can also benefit. The large DoD space industry, including USAF, MDA, NRO, and new Army nanosat programs at SMDC will directly benefit. Among these programs are AEHF upgrades, GPS follow-ons, MDA's STSS and PTSS, USAF TacSat family, Plug and Play (PnP) sats, Operationally Responsive Space (ORS), and Army SMDC nanosat family. The entire CubeSat initiative including NRO's Colony program would benefit. Our memory product will also address emerging MDA radiation threats. These programs include CKV, AKV, THAAD, AEGIS, MKV, and GMD for Blocks 2017 and beyond. A specific example here is the Common Kill Vehicle (CKV) where the advanced interceptor needs dense SDRAM. With the new challenge of atmospheric neutrons to High Altitude Airship (HAA) programs and NASA or Air Force UAV programs, this memory product could be a timely solution. Other military applications may include strategic missiles (Trident and Air Force Minuteman and MX upgrades), as well as many DoD tactical weapon programs with nuclear survival levels.","description":"Space Micro has developed the architecture for a radiation hardened memory subsystem that targets DDR3-and-beyond generations of DRAM. The architecture combines server platform error correction and memory buffer-on-board schemes with Space Micro proprietary techniques for radiation hardening and size, weight, and power reduction. During the NASA Phase I effort, Space Micro demonstrated two key elements of the architecture: (1) a scalable error correction coding (ECC) scheme that optimizes the robustness vs. efficiency vs. chip count tradespace, and (2) a Rad Hard By Design (RHBD) timing circuit for advanced DRAM fly-by routing. Space Micro has developed a Phase II plan for developing a server platform-like bridge chip that integrates ECC, interface logic, and timing circuitry into a high performance, low size, weight, and power (SWaP) memory subsystem suitable for next generation spacecraft computing.","startYear":2014,"startMonth":9,"endYear":2020,"endMonth":9,"statusDescription":"Completed","principalInvestigators":[{"contactId":2343175,"canUserEdit":false,"firstName":"Bert","lastName":"Vermeire","fullName":"Bert

Space Micro proposes to build a radiation hardened by design (RHBD) SDRAM memory, using a modified version of our HF-Core Memory Controller to solve all the single event effects issues (SEU, SEFI and multiple bit errors). The RHBD SDRAM will be manufactured on known radiation characterized eDRAM (embedded DRAM) ASIC processes: either TSMC or IBM for a Phase II demonstration. The resulting RH-eDRAM (our name for this device), fabricated on a 130 nm process, provides 128 Mbit of radiation hardened (SEU, SEFI, SEL and TID) memory, while a 90 nm IBM process would result in 512 Mbit of DRAM.
