DDR standalone memory controller?

[Drizzt]

Hi all.
Anyone knows where I can find infos on stand-alone memory controllers?
Do they exist? And how much are complex to use?


Thx

You mean like PCI cards that take RAM and act as solid state hard disk (Battery powered)?

No, no, I mean stand-alone DDR memory controllers.
To be solded on a PCB board, coupled with a bunch of resistors here, a bunch of capacitors there...

I thought most current (SDRAM onwards at least IIRC) memory controllers are found "inside" a northbridge chip, or inside the CPU (Opteron)?

Not going to happen. DDR is something like ~200 data pins, plus whatever data bus you use to get the data TO the controller. It's not something you just solder on. You'd never get the signal integrity good enough.
