  • Publication number: 20240069878
    Abstract: Aspects of the present disclosure provide a method for training a predictor that predicts performance of a plurality of machine learning (ML) models on platforms. For example, the method can include converting each of the ML models into a plurality of instructions or the instructions and a plurality of intermediate representations (IRs). The method can also include simulating execution of the instructions corresponding to each of the ML models on a platform and generating instruction performance reports. Each of the instruction performance reports can be associated with performance of the instructions corresponding to one of the ML models that are executed on the platform. The method can also include training the predictor with the instructions or the IRs as learning features and the instruction performance reports as learning labels, compiling the predictor into a library file, and storing the library file in a storage device.

  • Patent number: 9640259
    Abstract: A single-poly nonvolatile memory (NVM) cell includes a PMOS select transistor on a semiconductor substrate and a PMOS floating gate transistor series connected to the PMOS select transistor. The PMOS floating gate transistor comprises a floating gate and a gate oxide layer between the floating gate and the semiconductor substrate. A protector oxide layer covers and is indirect contact with the floating gate. A contact etch stop layer is disposed on the protector oxide layer such that the floating gate is isolated from the contact etch stop layer by the protector oxide layer.

  • Patent number: 8076708
    Abstract: A memory device and peripheral circuitry on a substrate are described, made by a process that includes forming a charge trapping structure having a first thickness over a first area. A first gate dielectric layer having a second thickness is formed for low-voltage transistors. A second gate dielectric layer having a third thickness, greater than the second thickness, is formed for high-voltage transistors. Polysilicon is deposited and patterned to define word lines and transistor gates. The thickness of the second gate dielectric layer in regions adjacent the gates, and over a source and drain regions, is reduced to a thickness that is close to that of the second thickness.
