1980 Spacelab Core Memory Module Revealed

SpaceLab, a startup focused on resilient computing for aerospace applications, has unveiled a new magnetic core memory module designed specifically for the harsh conditions of space. The product, dubbed “Core‑Space,” promises to combine the radiation‑hardness of traditional core memory with modern fabrication techniques to deliver high reliability in a compact, low‑power package. The announcement comes as the industry seeks alternatives to conventional semiconductor memories that are vulnerable to cosmic radiation and single‑event upsets.

Core‑Space is engineered to store 512 kilobits of data using a dense array of nanoscale magnetic toroids fabricated on a silicon substrate. According to SpaceLab, the memory achieves access times of 10 ns and operates at a supply voltage of 1.2 V, making it compatible with the power budgets of CubeSat and small satellite platforms. In preliminary tests, the module was subjected to proton and heavy‑ion irradiation levels exceeding those expected on low‑Earth orbit missions, and it maintained data integrity with no observed bit‑flips. SpaceLab also highlighted the module’s modular design, which allows for easy integration with existing flight‑ready processors and the potential for future scaling to larger capacities.

The introduction of Core‑Space underscores a growing trend toward hybrid memory solutions in space systems, where the trade‑offs between speed, power, and radiation tolerance are critical. By leveraging the proven robustness of magnetic core technology while incorporating modern semiconductor processes, SpaceLab aims to provide a dependable memory backbone for next‑generation space missions. The company plans to begin pilot deployments later this year, with a view to expanding the product line to support more demanding payloads and longer‑duration missions.
