I'm looking at using YAFFS in a product we are working on and I'm trying 
to understand the bit error rates of SLC nand devices.

All the docs I've read talk about bit errors that can occur.  Do these 
errors occur outside of a write/erase cycle?  Meaning that if I read the 
same page 100,000 times am I going to get a bit error?

Or are they only due to the oxide layer breakdown that occurs during an 
erase?

Any pointers to clear documentation on this would be appreciated.

Also does anyone here have any experience with using YAFFS and an Altera 
NIOS II setup?  I'm not using uCLinux.

Whats the current ram and rom requirements for the direct setup (no OS) 
and a 2k device.
