Tracking patterns during a semiconductor fabrication process includes: obtaining an image of a portion of a fabricated device; extracting contours of the portion of the fabricated device from the obtained image; aligning the extracted contour to a matching section of a reference design; decomposing the matching section of the reference design into one or more patterns; and updating a pattern tracking database with information pertaining to at least one pattern in the one or more patterns generated as a result of the decomposition.

A memory is encoded with data that represents a reference IC design, a retimed IC design, and logical relationships, wherein at least one logical relationship describes combinational logic without reference to structural information, such as actual cells that have been instantiated in the IC designs. The logical relationships are used to instantiate logic described therein, and to define one or more black boxes as being functionally inverse of the logic. Each instantiated logic and its functionally inverse black box are thereafter added to the reference IC design to obtain a transformed reference IC design. A transformed retimed IC design is also obtained by addition of the instantiated logic(s) and functionally inverse black box(es) to the retimed IC design. These two transformed IC designs are then supplied to an equivalence checker, for formal verification.

The performance of a bandgap reference circuit is improved by increasing the ΔVBE, and thereby correspondingly decreasing the input sensitivity of the error amplifier in the control loop. The ΔVBE can be increased by presenting stacked diode configurations at the amplifier inputs, by increasing the diode ratio presented at the amplifier inputs, and by providing a higher current in the CTAT leg than in the PTAT leg. The stacked diode configuration is achieved by producing isolated diodes with a triple well CMOS process. The stacked diode configuration and the triple well CMOS process also permit the input stage of the amplifier to use N-channel transistors operating in the threshold region.

As memory geometries continue to scale down, current density of magnetic tunnel junctions (MTJs) make conventional low current reading scheme problematic with regard to performance and reliability. A body-voltage sense circuit (BVSC) short pulse reading (SPR) circuit is described using body connected load transistors and a novel sensing circuit with second stage amplifier which allows for very short read pulses providing much higher read margins, less sensing time, and shorter sensing current pulses. Simulation results (using 65-nm CMOS model SPICE simulations) show that our technique can achieve 550 mV of read margin at 1 ns performance under a 1V supply voltage, which is greater than reference designs achieve at 5 ns performance.
