NAND memory problem

Tweet

I want to make a tablet costumized for a specific purpose. Now, i want to use this NAND memory MT29F16G08 with an AT91SAM9260 uC. The uC has only one CS line and the NAND memory needs 2. Can I use an output and make it work from the software(I want to write my own OS)? PS: I have good skills in electronics, but i'm not too good in programming and never worked with ARM, only some basics with AVR both C and asembly language. This project has more of an educational purpose so spare the "You will never do it" responses. If you can help me post, else go post somewhere else.
