can you cite an example of when DRAM is used for persistent storage? I am not aware of any.

  Did that thing ever actually ship?

    Yep, you could buy it new up until a couple years ago. http://www.amazon.com/Gigabyte-GC-RAMDISK-i-RAM-Hard-Drive/dp/B000EPM9NC/ref=sr_1_1?ie=UTF8&qid=1317834201&sr=8-1 http://www.amazon.com/Gigabyte-GC-RAMDISK-i-RAM-Hard-Drive/d...

There are a few products the use primarily DRAM, usually backed by capacitors/batteries and flash.

acid-state, http://acid-state.seize.it/ http://acid-state.seize.it/, which was previously known as happstack-state, and before that HAppS-State, has been doing it since 2005 or so. acid-state currently lacks replication/multimaster support, but happstack-state has had several experimental implementations of that as well. acid-state is Haskell specific.. but that is part of the appeal. You can directly store fancy algebraic data structures with acid-state. You are not limited to a simple combination of records integers and strings (for example).
