摘要： A log of error events associated with a memory device is maintained. Each error event included in the log is associated with one of multiple physical locations within the memory device. A physical location within the memory device is identified for background scanning based on the log of error events. A background scan is performed on the physical location identified based on the log of error events.

摘要： A failed erase operation is detected at a memory block of a memory device. Based on detecting the failed erase operation at the memory block, data on the memory block is destroyed using a data destruction algorithm that corrupts data stored by one or more cells of the block. The data on the memory block is verified to be destroyed. A passing data destruction status for the memory block is provided based on verifying the data on the memory block is destroyed.

摘要： Devices and techniques for NAND cell encoding to improve data integrity are disclosed herein. A high-temperature indicator is obtained and a write operation is received. The write operation is then performed on a NAND cell using a modified encoding in response to the high-temperature indicator. The modified encoding includes a reduced number of voltage distribution positions from an unmodified encoding without changing voltage distribution widths, where each voltage distribution corresponds to a discrete set of states an encoding.

摘要： Systems and methods are disclosed, including determining whether to write dummy data to a first physical page of memory cells of a storage system, such as in response to a detected asynchronous power loss (APL) at the storage system, using a determined number of zeros in the first physical page.

摘要： In an embodiment, a system includes a plurality of memory components and a processing device that is operatively coupled with the plurality of memory components. The processing device detects a triggering condition for updating one or more media settings of a memory component of the plurality of memory components, and responsively instructs the memory component to load, from data storage on the memory component, a set of one or more media-setting values that correspond to the one or more media settings of the memory component.

摘要： Devices and techniques for a flash memory block retirement policy are disclosed herein. In an example embodiment, a first memory block is removed from service in response to encountering a read error in the first memory block that exceeds a first error threshold. Recoverable data is copied from the first memory block to a second memory block. During each of multiple iterations, the first memory block is erased and programmed, and each page of the first memory block is read. In response to none of the pages exhibiting a read error that exceeds a second error threshold during the multiple iterations, the first memory block is returned to service.

摘要： Disclosed in some examples are methods, systems, memory devices, and machine readable mediums for performing an erase page check. For example, in response to an unexpected (e.g., an asynchronous) shutdown, the memory device may have one or more cells that did not finish programming. The memory device may detect these cells and erase them or mark them for erasure.
