Premium member Presentation Transcript MagnetoSparks™ : MagnetoSparks™ Flash Memory under Cosmic and Alpha Irradiation Presents Outline : Outline Introduction Cosmic Rays (CR) Digital Memories (CR) Indirect EMI to Digital Memories Experiment on Flash memory Experiment Results Conclusion Introduction : Introduction Different type of memories can NOT be used in all places. ًWhy NOT? Different Costs Different Storage concepts Different materials (limitation) Cosmic ray : Cosmic ray High energy radiation from outer space… B.B.Radiation Sun ..etc. Digital Memory : Digital Memory Types of memory: Flash memory Non-Volatile SRAM Type of RAM (Random..) Volatile Can cosmic rays cause error in memory? Yes (soft error) Which type of memories can stand against cosmic rays? Cosmic Rays Indirect EMI to Digital Memories : Cosmic Rays Indirect EMI to Digital Memories How? Single Event Upset Alpha vs. Cosmic Is it important to Choose! the type of memories that can be reliable in cosmic rays irradiation? Cosmic Rays Indirect EMI to Digital Memories : Cosmic Rays Indirect EMI to Digital Memories Why choosing the type of memory is important? Higher altitude more cosmic ray flux more cosmic ray strength Memories used in aircraft Experiment : Experiment EUT: 3 different types of flash memories (2 of each) Emitted radiation (protons) Data recorder (records log errors) Experiment : Experiment Why protons? Simulate cosmic ray neutrons with emitted protons. Easy to access Available in higher energy levels, unlike neutrons. Experiment : Experiment Procedure Array! Loop Methodology for Chip Erase and Program looping. Experiment Results: : Experiment Results: Experiment Results: : Experiment Results: Cosmic Ray FIT's by Device-60% UCL and 150 Mev 1 FIT=1 Failure Per Billion Device-Hours Conclusion : Conclusion Flash memories are more repayable than SRAM in case of Cosmic Ray Its better to use flash memories on aircraft SRAM technology should be improved Slide 14: Any Questions?
