Micron launches highest-density, radiation-tolerant NAND product for space missions.

Micron Technology has launched the industry's highest-density, radiation-tolerant single-layer cell (SLC) NAND product with a die capacity of 256 gigabits. This product is the first in a portfolio of space-qualified NAND, NOR, and DRAM solutions. The space economy is growing rapidly, driven by commercial and government missions, and the demand for high-performance technology capable of processing data directly in orbit. Micron's radiation-tolerant memory is essential for AI-enabled edge computing in space operations.

Boise, Idaho — July 22, 2025 — Micron Technology, Inc. (Nasdaq: MU), the leading U.S.-based memory manufacturer, has announced the launch of its industry's highest-density, radiation-tolerant single-layer cell (SLC) NAND flash memory with a die capacity of 256 gigabits (Gb). This product is the first in a portfolio of space-qualified NAND, NOR, and DRAM solutions designed to meet the growing demands of the space economy.

The space industry is experiencing rapid growth, driven by both commercial and government missions. As computing and AI technologies evolve, there is an increasing need for high-performance technology capable of processing data directly in orbit. AI-enabled edge computing is transforming space operations by allowing spacecraft to analyze sensor data, detect anomalies, and make decisions autonomously, reducing the reliance on Earth-based systems and preserving bandwidth.

Micron's radiation-tolerant memory is essential for these space operations. The new SLC NAND flash memory undergoes rigorous testing aligned with NASA's PEM-INST-001 Level 2 standards, including radiation characterization and extreme environment testing. This ensures that the memory can withstand the harsh conditions of space, including extreme temperatures, shock, vacuum pressure, and radiation exposure from solar energetic particles and galactic cosmic rays.

The product is already being used in NASA's Earth Surface Mineral Dust Source Investigation (EMIT) mission through Mercury Systems' solid-state data recorders. EMIT, an imaging spectrometer launched to the International Space Station in 2022, captures 100,000 spectra per second, demonstrating the reliability and long-term data storage capabilities of Micron's high-density, radiation-tolerant memory.

Micron's strategy to expand its aerospace industry support includes modernizing its U.S.-based manufacturing facilities and establishing specialized customer labs and technical support teams. This end-to-end supply chain control enhances security, traceability, and supply continuity, which are critical for aerospace and government contracts. The company plans to introduce additional space-qualified memory and storage solutions in the coming year to address the evolving demands of next-generation space missions.

This launch represents a strategic expansion into the rapidly growing space computing market. The 256Gb SLC NAND flash is significant as it is the first high-density radiation-tolerant memory from a major manufacturer, giving Micron a first-mover advantage in this specialized segment. This move capitalizes on two converging trends: the booming space economy and increasing demand for edge AI computing in orbit.
