Yes, it is possible Robert.
"Windows Vista offers the ReadyBoost technology, letting a flash drive store part of your paging file to increase system performance when you're low on RAM, but:
1.) It is NOT available for Windows XP or previous versions.
2.)
It is NOT a substitute for RAM, providing just a little extra boost."
"The key point is that the USB drive must have very fast seek times. Many USB flash memory devices, even those with high data transfer rates, don’t have sufficiently fast seek times to make them useful for ReadyBoost. Unfortunately, manufacturers don’t normally publish random seek times for flash memory like they do for hard disks. This makes shopping for a ReadyBoost compatible flash drive a bit of a lottery."
"It’s possible to force Windows to accept any device for ReadyBoost use via a registry hack. However,
this is not recommended, as the high latency will reduce system performance rather than improve it."
Anyway if you want to try this (I think that you almost for sure have some flash drive),
take a look to this instructions:- Plug any USB 2.0 flash memory drive that holds at least 256MB but no more than 4GB into your PC and Autoplay gives you a choice to invoke ReadyBoost, where Vista will use the drive's memory as an additional disk cache to speed things up. Just click Speed up My System and you're off and running.

- Also you have possibility to open Properties of your Flash drive and under ReadyBoost tab with slider change this value.

Hope this is enough explanation about this subject ?
