Storage - anything that can store data. ECC is a generic term and covers all 
kinds of checksumming algorithms. I was talking pretty generic - don't care 
if ram, caches, nand-flash, ficon or anything else. 

I was trying to get across that its hard to pinpoint where your bits flipped - 
in the storage device, on the transmission there or back.

Right - and again I was using generic terms because at the time that I posted, 
the question was if the RAM is bad or any other component... :)
