hmm I reread the firt post why is read so slow?? When I thought about
using nand I read that reading a byte took something like 50 ns. That is
like 20MB per second for an 8 bit device. This is in the region where it
did not pay to be smart,the accesses overhead to do read only what's
needed is greater than the time wasted reading uneccessary data.
