摘要： A read only memory (ROM) with redundancy and methods of use are provided. The ROM with redundancy includes a programmable array coupled to a repair circuit having one or more redundant repairs. The one or more redundant repairs include a word address match logic block, a data I/O address, and a tri-state buffer. The word address match logic block is provided to the tri-state buffer as a control input and the data I/O address is provided to the tri-state buffer as an input. An output of the tri-state buffer of each redundant repair is provided as a first input to one or more logic devices. One or more data outputs of a ROM bit cell array is provided as a second input to a respective one of the one or more logic devices.

摘要： Structures and methods for implementing alternating power gating in integrated circuits. A semiconductor structure includes a power gated circuit including a group of power gate switches and an alternating enable generator that generates enabling signals. Each respective one of the power gate switches is enabled by a respective one of the enabling signals. The alternating generator generates the enabling signals such that a first enabled power gate switch is alternated amongst the group of power gate switches.

摘要： Systems and methods for determining adjustable wafer acceptance criteria based on chip characteristics. The method includes measuring a density of at least one chip. The method further includes computing a difference in density between the density of the at least one chip and a density of at least one kerf structure. The method further includes calculating an offset value to modify a Wafer Acceptance Criteria (WAC) to match the density difference between the at least one chip and the at least one kerf structure. The method further includes applying the offset value to the WAC for a wafer level measurement in order to increase chip yield performance.

摘要： Systems and methods are provided to optimize critical paths by modulating systemic process variations, such as regional timing variations in IC designs. A method includes determining a physical location of an element in the semiconductor chip design within the critical path. The method further includes modulating a systemic process variation of the semiconductor chip design to speed up the critical path based on a polysilicon conductor perimeter density associated with the element.
