Laser trimming disabling various logic circuits. An example of this is the IBM POWER4 microprocessor where the chip contains five banks of cache memory but only requires four banks for full operation. During testing, each cache bank is exercised. If a defect is found in one bank, that bank can be disabled by blowing its programming fuse. This built-in redundancy allows higher chip yields than would be possible if all cache banks had to be perfect in every chip. If no bank is defective, a fuse can be blown arbitrarily, leaving just four banks. Laser trimming Laser trimming is the manufacturing process
