How can I interface an ARM chip with an external memory chip?

I have finished a project using an LPC2132 and quickly ran into problems with not having enough RAM (64k).

For my next开发者_如何学Go project, I'd like to avoid this problem all together by picking a chip that can interface with an external, larger memory chip. How can I do this or where are some resources that I could read up on this at? (I already did Google for about an hour)

Since this has no EMIF (External Memory Interface), you're kind of out of luck. The best thing I would suggest is using some SPI RAM (RAM you can interface over a SPI bus). You'll have to do special calls to read/write to it, so it won't be as transparent as declaring variables and getting extra RAM, but it's something.
