Podcast: Storage Developer Conference 2018 – Emerging Memories

SDC 2018 LogoAlmost one year ago Tom Coughlin and The Memory Guy presented the findings of our first emerging memories report at the Storage Networking Industry Association’s (SNIA) Storage Developers Conference (SDC).  The podcast of this presentation has just been made available on the SNIA website.

In the podcast, titled “The Long and Winding Road to Persistent Memories,” Tom and I reviewed leading emerging memory technologies as we had surveyed them for our report.

This is a highly visual presentation, so I would recommend following along with the slides, which can also be downloaded from the SNIA SDC website at HERE.  That same page combines the slides and the podcast into a video, so if you’re able to, it might be  a good idea to watch the video.  If you’re driving as your listening to it, though, then please use the podcast instead!

In the time since that podcast was recorded Tom and I have updated the report to a 2019 edition, which can be Continue reading

NV Memory Selectors: Forming the Known Unknowns (Part 3)

Ron NealeIn this third part of a four-part series, contributor Ron Neale continues his analysis of selector technologies focusing the nature of the mystery of Forming and a number of the many unanswered questions.


From Part 2 of this series it is very clear that only a detailed and accurate description of threshold switching will allow an assessment of what might be possible during the act of Forming, when the threshold voltage of a selector or memory (if the latter is fabricated in its amorphous state) is reduced in some cases by a factor more than 30% from its as-fabricated value. The problem is that there have been numerous attempts to account for the threshold switching mechanism. In Part 3 of this series I will briefly explore some of threshold switching options and search for any which might be used to account for Forming.

Threshold switching: The key.

If understanding what is happening during threshold switching is the key to what might be possible during that single cycle of threshold switching associated with selector Forming, then there is a possible converse connotation: If we really understand what is happening Continue reading
