    Abstract: A representative memory device includes a cell array, at least one break cell that subdivides the cell array into bit cell arrays, and one or more power switches that are electrically coupled to the bit cell. In one embodiment, the break cell separates a connectivity of a first voltage and a second voltage between at least two bit cell arrays so that the bit cell arrays can be selectively coupled to either the first voltage or the second voltage using the power switches. The power switches control the connection of each separated bit cell array of the cell array to either the first voltage or second voltage.

  • Publication number: 20130126982
    Abstract: A method for forming a semiconductor device such as a MOSFET. The method includes forming gate electrode pillars on a silicon substrate via material deposition and etching. Following the etching step to define the pillars, an epitaxial silicon film is grown on the substrate between the pillars prior to forming recesses in the substrate for the source/drain regions of the transistor. The epitaxial silicon film compensates for substrate material that may be lost during formation of the gate electrode pillars, thereby producing source/drain recesses having a configuration amenable to be filled uniformly with silicon for later forming the source/drain regions in the substrate.

  • Publication number: 20130074019
    Abstract: A method for verifying functionality of a system-on-chip (SoC) comprises modeling a system block in first and second models at a first level and a second level lower than the first level, respectively. A stimulus transaction is generated at a first testbench at the first level. The stimulus transaction is transmitted from the first testbench to a second testbench at the second level. The stimulus transaction is transformed into a first response transaction, using the first model, at the first level. The stimulus transaction received at the second testbench is transformed into a second response transaction, using the second model, at the second level. Functionality of the SoC at the first and second levels is verified based on the first and second response transactions.

    Abstract: A continuous-time delta-sigma digital-to-analog converter (DAC) includes a first delta-sigma modulator configured to quantize a most significant bit or bits of a digital input signal and produce a first quantization error signal, and a second multi-stage delta-sigma modulator configured to quantize less significant bits of the digital input signal. A first DAC is coupled to an output of the first delta-sigma modulator, and a second DAC is coupled to an output of the second noise-shaping filter. The second DAC has a greater resolution than the first DAC. A low pass output filter is coupled to a sum of an output of the first DAC and an output of the second DAC.
