I doubt it as well.  DRAM also has power-off memory persistence 
and nearly everyone in security ignores that as well.

But not the spooks :

"The FEI-374i-DRS is a data recovery system that captures and preserved
digital data, in its original format, directly from the Dynamic Random
Access Memory (DRAM) of Digital Telephone Answering Machines (DTAMs)
The FEI-374i-DRS is an indispensable tool for forensic investigators
required to evaluate residual audio and tag information retained in
today's DRAM-based DTAMs."
