    摘要: A phase-locked loop within an integrated circuit assembly is provided. The phase-locked loop includes a plurality of subcells of semiconductor devices arranged in a base layer pattern on base layers of the integrated circuit assembly. One or more metal layers are formed over and interconnect the plurality of semiconductor devices in a metallization pattern. The phase-locked loop has an output frequency range that is changeable with a change to the metallization pattern without a corresponding change to the base layer pattern.

    摘要: A disclosed embodiment is a programmable memory cell having improved IV characteristics comprising a thick oxide spacer transistor interposed between a programmable thin oxide antifuse and a thick oxide access transistor. The spacer transistor separates a rupture site formed during programming the programmable antifuse from the access transistor, so as to result in the improved IV characteristics. The programmable antifuse is proximate to one side of the spacer transistor, while the access transistor is proximate to an opposite side of the spacer transistor. The source region of the access transistor is coupled to ground, and the drain region of the access transistor also serves as the source region of the spacer transistor. The access transistor is coupled to a row line, while the spacer transistor and the programmable antifuse are coupled to a column line. The rupture site is formed during programming by applying a programming voltage to the programmable antifuse.

    摘要: A differential latch-based one time programmable memory cell is provided. The differential latch-based one time programmable memory cell includes a differential latching amplifier having a first set of fuse devices coupled to the first input and a second set of fuse devices coupled to the second input. Only one set of fuse devices can be programmed in a memory cell. If one or more fuse devices in a set of fuse devices are programmed, the side having the programmed fuse will present a lower voltage at its input to the differential latching amplifier. Differential latching amplifier outputs a “0” or a “1” depending on the side having the programmed fuse.

    摘要: An arrangement and method for making a gate array architecture locates the well taps at the outer corners of each gate cell. The power buses are also located at the outside of the gate cell as well, enabling sharing of the well taps and the power buses. The location of the well taps at the outside corners of the standard cell reduces the number of transistors in a single repeatable cell from eight transistors to four transistors.

A first voltage-controlled delay line coupled between the reference input and the feedback input and has a first delay, which is controlled by the voltage on the common node. A second voltage-controlled delay line is selectively coupled in series with the first delay line, between the reference input and the feedback input, as a function of a test control input. The second delay line has a second delay, which is controlled by the voltage on the common node.

The plurality of different threshold voltage layers may comprise at least one layer with a higher threshold voltage and at least one layer with a lower threshold voltage. The oxide may comprise a gate oxide. The bitcell may comprise an anti-fuse device. The layer with a higher threshold voltage may be separated from an output terminal of the bitcell by the at least one layer with a lower threshold voltage.

After programming, the memory cell operates as a one-time programmable non-volatile memory cell. The memory cell includes a storage element coupled at a first side to a first upper fuse and a first lower fuse and coupled at a second side to a second upper fuse and a second lower fuse. When the first upper fuse and second lower fuse are programmed, the storage element outputs a first value. When the second upper fuse and first lower fuse are programmed, the storage element outputs a second value. After programming the upper fuse acts as a pull-up fuse and the lower fuse acts as a pull-down fuse hold the state of the cell.

    摘要: The present invention provides a system and method for monitoring a short clock cycle on a semiconductor chip. The system includes a phase-locked loop (PLL) for receiving a reference clock as input and for outputting a PLL clock out. The system includes a delay-locked loop (DLL) for receiving the PLL clock out as input and for outputting a DLL phase offset clock. The DLL is locked to a frequency of the PLL clock out. The system may include an edge comparator for receiving the PLL clock out and the DLL phase offset clock as input. The edge comparator is suitable for monitoring each edge of the PLL clock out and each edge of the DLL phase offset clock, and for reporting a short clock cycle when an edge of the PLL clock out comes before an edge of the DLL phase offset clock.
