DDR3 ST-MRAM in Enterprise SSD
Utilizing Everspin ST-MRAM in an Enterprise SSD to greatly reduce power-fail energy storage while increasing SSD performance and density
Application Note: As Enterprise SSDs continue to push the envelope in terms of system performance and smaller form factors, SSD solutions providers are facing greater challenges to increase performance and density while continuing to protect data-in-flight from power failures. NAND flash has not significantly increased in performance and the improvement in SSD performance is typically made by adding more parallel channels of flash. This increases the need for energy storage for power fail protection which in turn reduces space available for the storage array for a fixed form factor.

Case Study: Skyera Solid State Storage Appliance
MRAM Eliminated Capacitor-Backed RAM
By using MRAM in its MLC NAND Flash-based enterprise solid-state storage systems, Skyera provide customers with enhanced data center fault recovery, reduced system downtime and lower total cost of ownership, without the drawbacks of capacitor-backed RAM solutions. The fast write speed and non-volatility of MRAM allowed Skyera to overcome any point of failure within the system memory while providing the best possible performance to enterprise-class applications.
MRAM in Enterprise SSD Applications
Compared to alternative non-volatile RAM solutions, MRAM eliminates the need for external components such as resistors, capacitors, batteries or super-capacitors including additional power fail logic circuitry. The elimination of these components improves data fidelity and system form factor while providing the most reliable solution at the overall lowest cost. By enhancing data center and networking fault recovery, MRAM can reduce system downtime and also simplify system design providing an overall lower total cost of ownership.
Case Study: Buffalo Memory SSD
Buffalo Memory Company, Ltd., a subsidiary of Buffalo, Inc., a worldwide leader in the storage, memory and network equipment market is now developing SSD's with ST-MRAM for the industrial market.
Buffalo Memory has been working on a highly reliable SSD for the industrial market and will strengthen its product line by releasing ST-MRAM cached SSD with 2.5inch form-factor and SATA3 interface in order to provide power fail endurance, higher speed and higher consistency.
