  • Patent number: 9379176
    Abstract: An integrated circuit containing a well resistor has STI field oxide and resistor dummy active areas in the well resistor. STI trenches are etched and filled with trench fill dielectric material. The trench fill dielectric material is removed from over the active areas by a CMP process, leaving STI field oxide in the STI trenches. Subsequently, dopants are implanted into a substrate in the well resistor area to form the well resistor. An integrated circuit containing a polysilicon resistor has STI field oxide and resistor dummy active areas in an area for the polysilicon resistor. A layer of polysilicon is formed and planarized by a CMP process. A polysilicon etch mask is formed over the CMP-planarized polysilicon layer to define the polysilicon resistor. A polysilicon etch process removes polysilicon in areas exposed by the polysilicon etch mask, leaving the polysilicon resistor.

  • Patent number: 7813198
    Abstract: One embodiment of the invention includes a memory system. The system comprises a memory cell coupled to a bit-line node. The memory cell can be configured to generate a bit-line current on the bit-line node in response to a bias voltage during a read operation. The system further comprises a sense amplifier configured to maintain a substantially constant voltage magnitude of the bit-line node during a pre-charge phase and a sense phase of the read operation based on regulating current flow to and from the bit-line node, and to determine a memory value of the flash memory transistor during the read operation based on a magnitude of the bit-line current on the bit-line node.
