As usual, classes will be held at our lovely Larkspur Landing location. Click on the image for booking information.
Before registering, take a look at some highlights students contributed from previous Guerrilla classes:
Attendees should bring their laptops, as course materials are provided on CD or flash drive. The venue also offers free wi-fi to the internet.

- They tested 45 different NAND flash chips from six vendors that ranged in size from 72 nm circuitry to the current 25nm technology.
- They then took their test results and extrapolated them to the year 2024, when NAND flash development road maps show flash circuitry is expected to be only 6.5nm in size. At that point, read/write latency is expected to increase by a factor of two or more.
- They did not use specialized NAND flash controllers such as those used by Intel, OCZ or Fusion-io. Their results can be viewed as "optimistic" because they didn't include latency added through error correction or garbage collection algorithms.
- Considering the diminishing returns on performance versus capacity, Grupp said, "it's not going to be viable to go past 6.5nm ... 2024 is the end."
The technical paper entitled, The Bleak Future of NAND Flash Memory (PDF), was presented and published at the FAST2012 conference held in San Jose, CA on February 14-17.
