I keep seeing an ad by a company called Legacy Electronics, Inc., which claims to have laptop SODIMM memory modules which use 30-50% less power, reducing heat and extending battery life.
The memory modules carry the brand name "CoolRAM".
Does anyone know if this claim is even remotely legit?
They have a fancy promotional site at:

The companies web site is:

Thanks to anyone with useful information!

Never heard of them but here is some info:

Less power consumption (20-50%
less in fact) means CoolRAMTM also
produces less heat. Which translates
to extended battery life when
compared to standard SDRAM
SODIMM operations.

STAYS COOL WHEN THE HEAT IS ON.
Notebook designers have a new, high-density, Small Outline Dual Inline Memory Module (SODIMM) option that incorporates Infineon Technologies® extended, low-power Synchronous Dynamic Random Access Memory (SDRAM) chip. Called CoolRAMTM, this 144-pin Mobile-RAM SODIMM uses a significantly reduced self-refresh current, as well as a lower operating current, lower burst operating current, and lower auto refresh current.
Sounds interesting but don't know if it really makes a difference. Are they more expensive than regular SO-DIMMS?
