  • Patent number: 10949300
    Abstract: Methods, systems, and devices for operating a memory cell or cells are described. An error in stored data may be detected by an error correction code (ECC) operation during sensing of the memory cells used to store the data. The error may be indicated in hardware by generating a measurable signal on an output node. For example, the voltage at the output node may be changed from a first value to a second value. A device monitoring the output node may determine an error has occurred for a set of data based at least in part on the change in the signal at the output node.
    Type: Grant
    Filed: October 30, 2019
    Date of Patent: March 16, 2021
    Assignee: Micron Technology, Inc.
