doh! thanks for your help! cant believe i foobared that, but i am happy
anyway :)

The Micron chips you referred to are 32MB, not kB.
How much do you exactly need ? The MT48LC4M16A2P sells for $2.38 at
digikey in 10,000 quantities, and is 8MB.
If you need kilobytes, you'll need an SRAM, since the SDRAMs aren't
that small.

I was hoping to only spend $1 to $2 for 32k SRAM (or SDRAM) to
interface with the AT91SAM9260. Looking at the schematic for the
AT91SAM9260 evaluation board, I can see it uses two Micron
MT48LC16M16A2 32KB SDRAM chips. Looking on digikey.com and avnet.com,
this chip is about $7 in quantities of 10,000, which is much too
expensive for the project.
Does anyone think I will be able to find 32KB SRAM (or SDRAM) that is
compatible with the AT91SAM9260, and that is around $2? I am pretty
newbie-ish whenit comes to SRAM/SDRAM so this question may come off as
very stupid. Thanks - mark
