1. A method of operating a cache comprising memory cells, the method comprising: setting a minimum operating voltage (Vcc min) of the cache to a voltage value at which the number of cells that fail in the cache is between approximately 0.1% and approximately 1% of the number of lines in the cache, while the remaining cells continue to function correctly at the voltage value chosen for Vcc min; and compensating for errors produced by memory cells in the cache that fail when operated at the voltage value chosen for Vcc min.
