Questions about future RAM
Well, not necessarily future, as the XServe already includes DDR SDRAM.
DDR RAM, as I have read here, can send or recieve two pieces of information each clock cycle, as opposed to the single one SDRAM pushes.
Why not just develop standard RAM that operates at a higher clockspeed? For instance, would a computer work best if all of its components had the same bandwidth - I mean, very little wasted time if every component operates at 1 GHz, for instance.
Nowadays, significant amounts of time are lost becuase the CPU spends much of its time waiting for data from the memory or longer for the HD.
Is it imposible for RAM to operate at that speed, becuase it is physically larger than a microprocessor? I remember that electrical charges travel about a foot in a nanosecond. Each clock cylce in a 1 GHz system is one nanosecond. So components must be close - minimum one cycle is wasted waiting for info.
Does operation of RAM consume significant electricity and therefore make significant heat, like a CPU does? What about MRAM?
What electronic components is modern RAM made of? Mostly capacitors?
