  • Dummy bitline circuitry
    Patent number: 11232833
    Abstract: A circuit includes a dummy wordline, a dummy bitline, and a dummy cell coupled to the dummy bitline. The dummy cell includes an active pulldown nMOSFET and a pass nMOSFET having a gate connected to the dummy wordline, a first source terminal connected to the drain terminal of the active pulldown nMOSFET, and a drain terminal connected to the dummy bitline. The circuit further includes a substrate-connected dummy bitline coupled to the source terminal of each active pulldown nMOSFET and coupled to a substrate.

  • Routing structures for memory applications
    Patent number: 10839861
    Abstract: Various implementations described herein are directed to an integrated circuit having multiple banks of memory cells and a local input/output (IO) component for each bank of the multiple banks. The integrated circuit may include multiple signal lines that are coupled to the multiple banks with the local IO components. At least one signal line of the multiple signal lines is wider than one or more of the other signal lines.
