Abstract:
In an integrated circuit chip having a programmable reference data table for holding information used to control at least one circuit block in said chip, a method of improving the performance of said chip comprising(A) testing said chip to determine at least two data selected from the group consisting of different operating voltages, different clock speeds, different back-bias voltages, different data bus widths, different power latency values, and mixtures thereof; and (B) entering at least two values based on said data into said reference data table using a non-volatile memory method or an anti-fuse method, whereby a signal from said at least one circuit block is sent to a monitor circuit, which accesses data from said reference data table and uses said data accessed from said reference data table to determine which circuit blocks will be used and conditions needed to attain the desired performance.
