DDR2 voltages: 1.8, 1.9, 2.0, 2.1, 2.2 -- What's the difference?

I'm looking at DDR2 RAM for my motherboard (Asus P5Q-E) and I see all sorts of voltages and voltage ranges advertised.<BR><BR>It looks like JEDEC standard is 1.8v, but I was curious about the memory ...

A Summary Of The DDR Memory Controller Standard—Wait, There Isn’t One!

The number of systems-on-a-chip (SoCs) that require an interface to off-chip memory is increasing. As a result, more and more designers are turning to double-data-rate (DDR) SDRAM interfaces such as ...
