M+ SPACE - RADIATION TOLERANT SSDs

---

Operating in space is unlike any other environment. Electronics are exposed to intense radiation, extreme temperature swings, vacuum conditions, and violent launch vibrations. In orbit, there are no second chances, no repairs, and no room for data loss.

That’s why MEMKOR M+ SPACE SSDs are designed from the ground up to endure the harsh realities of space while delivering high performance, high endurance, and mission-critical data integrity.

The Challenges of Space-grade SSDs and data storage

1. Radiation Exposure (SEU, SEFI, TID)

Radiation is one of the most destructive forces acting on space electronics. Energetic particles can cause:

• Single Event Upsets (SEU): Bit errors from particle strikes on memory cells.
• Single Event Functional Interrupts (SEFI): Temporary controller lockups or resets.
• Total Ionizing Dose (TID): Gradual performance degradation as radiation accumulates over time.

How MEMKOR Solves It:

M+ SPACE SSDs feature proprietary multi-layer ECC algorithms and a custom Space NAND Controller engineered to detect and correct SEUs in real time, recover from SEFIs, and maintain stable operation under high TID exposure.

2. Extreme Temperatures

Space environments swing between scorching heat and freezing cold amplifying thermal stress on components.

How MEMKOR Solves It:

Every M+ SPACE SSD is built with radiation-tolerant components and thermally optimized packaging, ensuring stable operation across extreme temperature ranges and during rapid thermal transitions.

3. Mechanical Stress and Launch Vibration

Launch sequences subject storage devices to intense shock and vibration that can damage connectors, solder joints, and flash assemblies.

How MEMKOR Solves It:

MEMKOR leverages its defense-grade mechanical design heritage using ruggedized enclosures, vibration-resistant connectors, and reinforced assembly techniques to guarantee survivability through launch and deployment.

4. Endurance and Data Integrity over Long Missions

Space systems must perform for years without maintenance or refresh cycles. NAND flash wear-out, bad blocks, and uncorrected errors can jeopardize mission data.

How MEMKOR Solves It:

With up to 60K program/erase cycles (PEC) and intelligent bad block management, M+ SPACE SSDs deliver exceptional write endurance and predictable long-term reliability. Proprietary wear-leveling ensures even utilization of flash cells, extending operational life.

5. Integration and Cost Constraints

Traditional rad-hard components can be prohibitively expensive and limited in capacity. Missions increasingly need space-grade COTS (Commercial-Off-The-Shelf) solutions that balance cost, performance, and qualification requirements.

How MEMKOR Solves It:

M+ SPACE SSDs are designed with Space-grade COTS components, providing rad-tolerant performance at lower program costs. Custom form factors, a locked Bill-of-Materials, and the inclusion of a basic file system give engineers deployment flexibility and stable long-term supply.
