    摘要: Methods of operating a memory device having embedded leak checks may mitigate data loss events due to access line defects, and may facilitate improved power consumption characteristics. Such methods might include applying a program pulse to a selected access line coupled to a memory cell selected for programming, verifying whether the selected memory cell has reached a desired data state, bringing the selected access line to a first voltage, applying a second voltage to an unselected access line, applying a reference current to the selected access line, and determining if a current flow between the selected access line and the unselected access line is greater than the reference current.

    摘要: Methods, systems, and devices for a refresh operation of a memory cell are described. A memory device may include a plurality of rows of memory cells. Each row of memory cells may undergo a quantity of access operations (e.g., read operations, write operations). During a read operation, a logic state of one or more memory cells may be determined by applying a read pulse having a first polarity. Based on the one or more memory cells storing a particular logic state (e.g., a first logic state), a refresh operation may be performed. During a refresh operation, a refresh pulse having a second polarity (e.g., a different polarity than the first polarity) may be applied to the one or more memory cells.
