RAM display

As I compose my own Obj-C program to do this manually for me; I am trying to find a freeware application that will attach itself to a running process and display it's stack segment for me in at least two basic columns/fields; address and memory (what's stored here). Solutions?

Edit: I know about the "Top" utility, and while useful it doesn't actually display the two more crucial parts I'd like it to (e.g. address and memory).
