Can someone give a link to the 4-bit ECC algorithm?

I need to implement one for the built-in Nand Flash driver.

Best of all, most likely, is the Reed Solomon Code . Here is a pretty good explanation of how they work, and here is some code that actually implements the algorithm. This is not very well commented, sorry. Some google action will be displayed more.

Good luck.

NAND Flash provides reference implementations. Check out the implementations in the U-boot and Linux kernel repositories.
