Does TME of vPro make a locked screen more secure?

vPro offers "Total Memory Encryption" (TME), which encrypts RAM and system bus data while the computer is on.

 

Does TME encryption improve the security of a computer when its screen is locked? That is, the computer is harder to attack because the RAM is encrypted behind the locked screen.

 

Can anyone confirm that TME enhances the security of the screen lock function of a computer?

TME encrypts all bus transfers and memory content. This protects against physical-presence attacks via, for example, bus or DIMM probing. This doesn't make the Windows screen locking mechanism any more secure, however.
