'Fraid not. SDRAM manufacturers are just now planning the transition
between 2.5v and 1.8v cores.

The reason is pretty simple: cell capacitance is limited, and the
charge available to store a bit is greater if you use more voltage.
Given the huge cost of SDRAM process development and the razor-thin
margins, you're not going to see special low-voltage versions.
