Everspin Technologies, Inc.‘s (NASDAQ: MRAM) partner Cobham Advanced Electronic Solutions (CAES) recently presented a technical case study describing the versatility and performance of their jointly developed Toggle MRAM for space applications. Cobham Advanced Electronic Solutions is a worldwide leader in the space memory market and ships production-grade, space-qualified Magnetoresistive Random Access Memory (MRAM) based on Everspin’s world-class technology to provide the space industry with radiation-hardened, highly reliable non-volatile memory that is immune to Single Event Upsets (SEU), low voltage Single Event Latchup (SEL), and Single Event Gate Rupture (SEGR). The products also provide unlimited endurance and a greater than 20-year retention across the -40° C to +105° C temperature range.
“Everspin’s MRAM technology has proven itself in the market with a production track record of high performance and endurance, providing superior non-volatile data retention to handle a variety of space mission-critical memory workloads,” said David Meyouhas, Director of Standard Product Marketing, Space and Semiconductor Solutions, Cobham Advanced Electronic Solutions. “We are delighted by our long-term partnership with Everspin that enables us to supply space-qualified Toggle MRAM solutions to the space industry, thereby addressing their needs for high performance, radiation-hardened, persistent memory that can operate in harsh environments. Cobham Advanced Electronic Solutions’ 16Mb and 64Mb Multi-Chip Module MRAM devices currently boast more than 144 space application design-ins, proven flight heritage, and coverage at over 70 customers.”
The Cobham case study delves into Toggle MRAM strengths, including the following:
- Radiation Hardness (RadHard) of greater than 1Mrad (Si) TID
- Endurance cycles of greater than >20 years (i.e. unlimited)
- Data Retention rates of over 20 years , which is beyond mission lifetimes
- High speed read/write of 45ns
- QML-Q; and QML-Q+ Quality and Reliability
