Stanford Talk on Flash Memory Design

Posted by VIOLIN SYSTEMS on Mar 15, 2012 3:36:34 PM

Back to school day.

Over at Stanford they have a speaker series that has been going on for the last few... decades, called the  Stanford University Department of Electrical Engineering Computer Systems Colloquium, known to many simply as EE380. The list of past speakers is as they say, long and distinguished, and includes such industry lightweights as Joy, Lamport, Colwell, Bechtolsheim, Gray, Metcalfe, Gelsinger, Hennessy, Patterson, Brin & Page, Diffie, Mashy, Wolfram, Cerf and Kay. For a mere mortal being invited to give an EE380 talk can be an intimidating experience, which they try to make easier by telling you that there will probably be no more than 50 people in the room, thankfully they didn't mention that 10,000 people will watch the web cast online until after my talk was over. Yes, the other day Bennett and Rowett were added to the list of "past EE380 speakers."

Flash in the Data Center? Part 1 – Roll your own and Garbage Collection

Posted by VIOLIN SYSTEMS on Sep 26, 2011 8:08:04 PM

Flash is coming to the data center. Contrary to perception 18 months ago, now this seems to be accepted as ‘common knowledge.’ There is still much discussion around what that flash will look like and in what form it will be consumed. I plan to write a series of blogs describing the unique challenges involved in building large flash Memory Arrays and some of the decisions made along the road. A good place to start with is the “let’s build it myself” group of folks and the challenges they will encounter.
The very adventuresome amongst you might start with, "I'll just make my own".
