Cobham Advanced Electronic Solutions is a provider in the space memory market and ships production-grade, space-qualified MRAM based on Everspin’s technology to provide the space industry with radiation hardened, 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, standard product marketing, space and semiconductor solutions, Cobham. “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.

Cobham case study delves into Toggle MRAM strengths, including:

  • 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

  • R/W of 45ns

  • QML-Q; and QML-Q+ quality and reliability

Case study

We are pleased to be working with Cobham to deliver persistent memory solutions to the space industry,” said Troy Winslow, VP, sales and marketing, Everspin. “Our Toggle MRAM technology delivers unprecedented quality and reliability for a non-volatile memory, making it a key building block component for mission-critical applications.

Everspin 8 Bit 16 Bit Parallel Interface Mram

Everspin offers a complete portfolio of Toggle MRAM devices, spanning 128Kb to 32Mb in serial and parallel interfaces and several packaging options. These products deliver fast read and write access speeds, 20-year data retention, and provide unlimited cycle endurance for reads and writes across temperatures ranging from -40°C to +125°C.

They are available in both BGA and TSOP standard package types for design and system flexibility. Everspin also offers 256Mb and 1Gb Spin-transfer Torque (STT) MRAM devices.
