SDRAM controller.

Hi Guys,

I am writing a SDRAM controller (for the first time), its a Micron
MT48LC16M16 sdram. I am having a little trouble coding it, i've written
some code for it but i am not sure if i am going along the right path
or not ? Does neone has a little tutorial on how to code a sdram
controller or perhaps a sdram controller that they wrote (doesnt matter
for which SDRAM), nething that i could use as a reference to learn
more. Ne help would be appreciated !! Thanks.

You can take a look at this one in opencores.org -->

HOw about Xilinx's SDRAM controller.  I'm pretty sure the source is on 
their website along with the app-note.

I am using the exact same RAM with Ateras SDRAM controller, which has
source with it. Are you doing this just for academic purposes? I would
suggest looking at their core, just because I know it works :)
