Are DDR and DDR2 SODIMMs interchangeable?

Good afternoon all,

I'm trying to upgrade my toshiba laptop that came with 512 megs of RAM.
This laptop uses DDR333 SODIMMs which are roughly 30% more expensive
than equivalent DDR2 sticks. The question is, are DDR2 chips backwards
compatible? The DDR and DDR2 SODIMMs both have 200 pins so I'm hopeful.
I couldn't find anything conclusive though.

I'd appreciate any advice.


Thanks.
