Avalanche Technology and NHanced Semiconductors Deliver Space Grade MRAM Boot Solution for Rad-Hard System-in-Package Integration

Avalanche Technology, Inc. and NHanced Semiconductors, Inc. are building a new rad-hard system-in-package FPGA integration designed to enable satellite and defense missions with dependable standby capability and high-confidence operational performance.Avalanche Technology treaffirmed its leadership as the provider of truly Space Grade NVM, delivering solutions that meet all 5 criteria required for missions: ‘Survive. Retain. Endure. Commit. Proven’.

While many technologies claim to be ‘Space Grade,’ true Space Grade requires that 5 objective criteria be met simultaneously. Space Grade technology must:

• withstand radiation without disruption
• retain data for the life of a mission
• endure unlimited writes
• commit data instantly, and
• demonstrate real heritage

In space systems, a technology that survives radiation but loses data, wears out over time, delays data commitment, or lacks flight heritage is not Space Grade. Partial compliance leads to failure. The company’s Space Grade MRAM uniquely delivers on all 5 criteria through inherent radiation immunity, permanent data retention, unlimited endurance, deterministic writes in nanoseconds, and proven flight qualification, without tradeoffs. Today’s announcement with NHanced focuses on 3 of these criteria: Survive, Retain, Proven.

NHanced was seeking a reliable, Space Grade boot solution for its new rad-hard FPGA system-in-package integration, and selected Avalanche MRAM after other evaluated options fell short.

“We evaluated multiple solutions and picked Space Grade from Avalanche,” said Bob Patti, president, NHanced Semiconductors. “Avalanche’s memory architecture is radiation-immune, with error detection and correction built directly into the memory die. This allows radiation-induced errors to be handled seamlessly without system resets or data loss, reducing the complexity of integration and ensuring the boot memory operates reliably in harsh space environments.”

Avalanche’s non-volatile MRAM also guarantees long-term retention of mission-critical data through power interruptions and the extreme temperature and radiation conditions experienced in both low earth orbit and deep space. Its deterministic write behavior ensures that individual data writes complete in nanoseconds, minimizing the risk of corruption during power interruptions and firmware over the air updates. These capabilities, verified across extended durations in representative space conditions, give NHanced a proven, flight-ready memory solution that simplifies integration while ensuring reliability for mission-critical boot operations.

“We’re enabling the first of many FPGAs & SOCs with integrated Space Grade memory,” said Paul Chopelas, GM, space and defense, Avalanche Technology. “Avalanche’s Space Grade architecture was the only solution that fulfilled NHanced’s memory requirements. We’re proud to partner with NHanced to enable the deployment of a new generation of rad-hard FPGAs in satellite and defense applications.“
