Storage Solutions craving ST-MRAM:
• ST-MRAM complements solid state & magnetic storage
• Improved response time due to low latency & high bandwidth
Solving Enterprise Storage data integrity issues
• Number 1 Priority: Cannot lose data if power fails !
• Historically using batteries/caps to protect data in RAM
Power Disruption Decision Time:
MRAM Manages Power Down Issues
• Avoid the Panic - keep the data in a true NV Memory with unlimited endurance
• Unlimited endurance allows critical data to be written whenever it changes
• No need to save on power fail when the data is already in MRAM
• No external Vcap, batteries or Super Caps required
• Eliminates external power storage that keeps the system alive for a few precious milliseconds which saves $$
• Reduced power management and software
• Power fail detection can be simpler
• Simplifies the power fail interrupt
• Use MRAM as the working memory
Enterprise SSD
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. Theelimination 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.
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.
