Abstract: A configuration setting manager of a memory device receives a request to perform an adjustment operation on a set of configuration setting values for the memory device, where each configuration setting value of the set of configuration setting values is stored in a corresponding configuration register of a set of configuration registers; determines a configuration adjustment definition associated with one or more configuration setting values of the set of configuration setting values; calculates an updated set of configuration setting values by applying a multiplier value to the configuration adjustment definition, wherein the multiplier value is associated with a number of programming operations performed on the memory device; and stores the updated set of configuration setting values in the corresponding configuration registers.

Abstract: An asynchronous power loss (APL) event is detected at a memory device. A last written page is identified in the memory device in response to detecting the APL event.

Abstract: In one embodiment, a system maintains metadata associating each block of a plurality of blocks of the memory device with a corresponding frequency access group, where each frequency access group is associated with a corresponding scan frequency. The system determines that a first predetermined time period has elapsed since a last scan operation performed with respect to one or more blocks of the memory device, where the first predetermined time period specifies a first scan frequency. The system selects, based on the metadata, at least one block from a first frequency access group associated with the first scan frequency. The system performs a scan operation with respect to the selected block.

Abstract: An amount of threshold voltage distribution shift is determined. The threshold voltage distribution shift corresponds to an amount of time after programming of a reference page of a block of a memory device. A program-verify voltage is adjusted based on the amount of threshold voltage distribution shift to obtain an adjusted program-verify voltage. Using the adjusted program-verify voltage, a temporally subsequent page of the block is programmed at a time corresponding to the amount of time after the programming of the reference page.

Abstract: Disclosed in some examples, are methods, systems, and machine readable mediums which compensate for read-disturb effects by shifting the read voltages used to read the value in a NAND cell based upon a read counter. For example, the NAND memory device may have a read counter that corresponds to a group of NAND cells (e.g., a page, a block, a superblock). Anytime a NAND cell in the group is read, the read counter may be incremented. The read voltage, Vread, may be adjusted based on the read counter to account for the read disturb voltage.

The monitored parameters can include parameters related to a selected time interval and measurements of read, erase, or write operations of the memory device. Additional apparatus, systems, and methods are disclosed.
