woggut, die, dies, dice; from your URL -
In the second stage of wafer manufacturing, each die on a fabricated wafer is tested for functionality. The dice that fail are marked with an ink spot. The wafer is then sectioned into individual die by scribing lines between the dice and breaking the wafer along these lines. The defective dice are discarded, and the remaining dice are usually sent from the fabrication facility to a die bank inventory
Semicon's experience is that die is its own plural. Often I hear dies as the plural of die. If you go back to the predecessor English concept (gaming dice, or dice used to stamp out sheet metal) then dice is the plural.
Common usage apparently has not settled on a single correct usage yet. 'Dice' would be the historic favorite, but follows Latin plurals (I think) rather than English. 'Dies' is already in use as a verb with different meaning. 'Die' as its own plural would represent an unusual English usage, but there are such examples ('sheep', for instance).
In the above usage a die bank would be a depository for defective dice. Different thing.
