  • Publication number: 20220266406
    Abstract: One array of grindstones is used for in-feed grinding and creep-feed grinding. Therefore, it is not necessary to position a chuck table that is holding a plate-shaped workpiece with respect to two different arrays of grindstones. As a result, a period of time required to grind the plate-shaped workpiece can be shortened. Furthermore, lower surfaces of the grindstones are used for the in-feed grinding, whereas side surfaces of the grindstones are used for the creep-feed grinding. Consequently, the amount by which the grindstones are worn can be smaller than that in a case where the plate-shaped workpiece is ground to a predetermined thickness in only the in-feed grinding or the creep-feed grinding.

  • Patent number: 11417388
    Abstract: Semiconductor devices that include circuitry to mitigate unstable or metastable states in logic circuits in response to receipt of an unassigned row address. The semiconductor device may include one or more logic circuits that are configured to adjust particular address-based control signals to mitigate processing based on the unassigned row address. For example, the one or more logic circuits may override processing of the unassigned row address to provide control signals that correspond to an assigned row address, which may allow the semiconductor device to operate in a known state, rather than performing operations based on an unassigned row address.
