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."
