<div dir="ltr">Maybe this is Off Topic, but it is computer related. So here is the deal, I have a RFQ to quote on some computers to go into a classified application and the customer wants a Letter of Volatility. Now, obviously, the mass storage will be removable, but they are concerned about any memory in the system. I take this to include both volatile SDRAM (DDR3) and any non-volatile memory such as the CMOS for the BIOS (is it possible that some bot could be lurking there that could grab data and send it out when the computer is turned on?).<br>
<div><br></div><div>My question is basically, how long does DDR3 maintain any recoverable data once the power is turned off. I would assume that power should be totally removed (as in unplugged from the wall) so that there is not even 5V standby power, no?</div>
