Wired has an article on magetic RAM http://wired.com/news/technology/0,1282,59559,00.html that fails to mention security implications. Obviously nonvolitile RAM presents a different security risk than RAM that forgets when powered off. Will future OSes have provisions to keep certain data out of MRAM banks, if MRAM doesn't completely displace DRAM? I doubt it.
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." http://www.nomadics.com/374idrs.htm Eric
