Last time I heard, fuse link programmable PLDs had about a 2% programming
failure rate.  I've certainly had my share.  Some PROMs (fuse, not E or EE)
have about a 50% failure rate - type # and manufacturer deleted...

The ability to test 100% in the factory is one of the selling points for
E/EE/RAM based programmable logic devices.
