Flash Memory Drives from Smart Modular Technologies

SMART Modular Technologies, Inc., a division of SGH and in memory solutions, SSDs, and advanced memory, announces a proprietary technology to mitigate the adverse impact of single event upsets (SEUs) in high-reliability flash-memory based systems.

SMART Modular’s MP3000 NVMe SSD products with SEU mitigation reduce annual failure rates from as high as 17.500/million units to less than 10/million units and can save hundreds of thousands of dollars in potential service costs by helping to ensure hundreds of hours of uninterrupted uptime, especially important for tough-to-repair remote deployments.

MP3000 PCIe/NVMe and ME2 SATA product portfolios include SEU mitigation technology to protect vs. system failures in the field.

“Our industry standard SATA and PCIe NVMe boot drives can slash annual failure rates by as much 99.7% by recovering from sof errors due to single event upsets,” states Satya Iyer, VP of specialty memory. “In networking and telecom applications in remote and hard-to-service locations, SEU mitigation and the ability to recover from soft errors can make the difference for systems that require 24/7 uptime.”

SEUs are an inadvertent change in “bit status” that occurs in digital systems when high-energy neutrons, or alpha particles, randomly strike and cause bits in memory – logic components – to literally flip their state. These high-energy particles can originate from terrestrial or extraterrestrial sources such as cosmic rays. They can lead to abnormal operation of digital systems or total system failure. Addressing these errors or upsets within the SSD enable recovery without the need for a full system reboot which is critical in terms of maintaining reliable operations and uninterrupted runtimes.

The SEU mitigation technology is superior to other solutions that simply rely on ECC for the internal SRAM. By having the ability to gracefully reboot itself without a host system reboot, the SSD also handles possible flipped bits in other components within the SSD which might account for an additional 10% of failures. Designed for applications that require maximum uptime, these boot drives with SEU mitigation come in storage capacity ranges from 60GB to 1.92TB, and are available in commercial and industrial temperature grades.

The ME2 SATA
M.2 and mSATA drives with SEU mitigation provide 60GB to 1.92TB of storage and are available in commercial grades (operating temperature: 0 to 70°C) and industrial grades (operating temperature: -40 to 85°C). The M.2 2280 also supports SafeDATA power loss data protection.

The MP3000 NVMe PCIe drives with SEU mitigation provide 80GB to 1.92TB of storage in M.2 2280, M.2 22110 and E1.S form factors and are available in commercial temperature grades (operating temperature: 0 to 70°C) and industrial temperature grades (operating temperature: -40 to 85°C). They also support SafeDATA power loss data protection.
