This wasn't really on DRAM in the same way as the paper is, interesting though that project was. Sadly, it's more or less defunct. The academic research at UVa has largely come to an end and Micron spun out the project to a startup that seems to be moribund (http://www.naturalsemi.com/).

I tracked these guys because we were doing automata in s/w (the https://github.com/intel/hyperscan project at Intel). There were some aspects of their methodology I didn't like (notably, they tended to run benchmarks that spewed matches, slowing Hyperscan down, while turning off matches on the h/w card!) but I found them v. interesting and they had some really thought-provoking stuff.
