Buffalo puts MRAM into SSD cache
Editor:- May 21, 2012 - Buffalo Technology is using a hybrid nvm approach in a new design of SSD - according to a report in Tom's Hardware - which says the company will use MRAM in its cache.

Editor's comments:- this was anticipated in my 2008 article - the Flash SSD Performance Roadmap.

The RAM cache flash ratio in SSDs varies from close to zero (skinny) upto 100%.

More RAM makes it easier for designers to meet symmetry goals which are desireable in some applications - but it also creates additional cost and complexity in the sudden power loss management subsystem.

RAMlike NVMs such as MRAM aren't a golden bullet either - but by compressing the time window required to maintain holdup for critical save operations from milli-seconds to microsends (and cleaning up the state on the next restart) such chips can enable a smaller footprint than other approaches.

At the other end of the spectrum - designers of skinny cache controller architecture can achieve the same in-system apps results with virtually no RAM. So - as usual in SSDs - you will see a diversity of approaches in competing SSDs.
