I'm using an iMX53 and I have designed for two DDR3 chips of 2Gb (128M-bit x 16) giving a total of 512MBytes of RAM.
My question is on how to lay out the PCB.
The CPU has the ability to do read and write leveling which means I can use a "fly-by" topology. But, because i'm using only two RAM chips i'm thinking that it would be far easier to use a balanced line or tree type topology that i would use on DDR2.
What would you advise?
