Persistent Memory: enabling cold boot attacks is a feature not a flaw.
Meg Whitman dropped a pair of teasers in the latest earnings call, with a new hyperconverged appliance mentioned plus a persistent memory game-changer. What is that? It's an hor d'oeuvre before the XPoint entrée. Persistent memory is a holy grail, the hoped-for love child of DRAM and non-volatility that meshes forgetful …

What was it called??
Back in the 60's and 70's it was called "core" memory and it had nice little donuts (insert Homer Simpson quote: "Mmmm Good!") that were magnetized as ones and zeros.
What goes around, comes around.
Yes, I even did work on machines that had these nice devices. I used the fact of persistence to keep accounting data across restarts to make sure the bills were paid, even if the machine crashed. they were speedy at the time. Not by today's standards, but 1.33 MHz clock rates for 32 bits was reasonable in the 60's

SanDisk's ULLtraDIMM is not persistent memory
Nice article, one correction though:
Diablo NVDIMM (SanDisk's ULLtraDIMM) is NVDIMM-F, which is a Flash block device on the memory channel.
Micron, Netlist, Smart, Viking etc. have NVDIMM-N, which is persistent memory.
Software for persistent memory, such as from Microsoft, HPE and Plexistor runs on the latter (NVDIMM-N).
