Latest Patents

Choi is credited with 1 patent, titled “Mask Revision ID Code Circuit.” The invention describes a mask identification bit circuit that supplies one of two potentials, VGND or VPWR, to a sense node. It uses links arranged in series, with each link configurable either for direct connections or cross-coupled connections between its inputs and outputs. Cross-coupling can switch the potential supplied to the sense node, and changing the configurations of multiple links allows the potential to switch more than once. The patent explains that n mask ID bit circuits can provide as many as 2ⁿ distinct mask identification codes.
