  • Integrated circuits having improved split-gate nonvolatile memory devices and methods for fabrication of same
    Patent number: 9362297
    Abstract: Integrated circuits are provided. An exemplary integrated circuit includes a source/drain region in a semiconductor substrate. The integrated circuit includes a charge storage structure overlying the semiconductor substrate and having a first sidewall overlying the source/drain region. The integrated circuit also includes a control gate overlying the source/drain region. Further, the integrated circuit includes a first select gate overlying the semiconductor substrate and adjacent the first sidewall. A first memory cell is formed by the control gate and the first select gate.
    Type: Grant
