Abstract: A method for performing a media scan operation on a virtual block in a memory device is described herein. The method includes incrementing a first count value of a first read counter via a controller in response to a first read operation performed on a first fractional good block of the virtual block. The method also includes incrementing a second count value of a second read counter via the controller in response to a second read operation performed on a second fractional good block of the virtual block. The method also includes selecting one of the first and second fractional good blocks for the media scan operation via the controller based on a difference between the first and second count values. The method further includes performing the media scan operation on a wordline of the selected one of the first and second fractional good blocks via the controller.

Abstract: A memory sub-system controller selectively adjusts read threshold voltages on certain word lines for partially written memory blocks of a memory sub-system. The controller generates a request to read a portion of a set of memory components. The controller, in response to determining that the portion corresponds to a partially programmed block (PB), selectively modifies a boundary word line (WL) read level offset, stored in a boundary WL offset table, by applying an adjustment factor to the boundary WL read level offset. The controller reads a first set of data from one or more inner WLs of the portion using a first read level offset retrieved from an inner WL offset table and reads a second set of data from a boundary WL of the portion using the selectively modified boundary WL read level offset.

Abstract: One or more media management threshold values associated with the memory device are maintained. The one or more media management threshold values include a bit error count per page threshold and/or a valley width threshold value. A number of program erase cycles associated with the memory device is identified. Responsive to determining that the number of program erase cycles satisfies a criterion, one or more adjusted media management threshold values are generated by decreasing the one or more media management threshold values as the number of program erase cycles increases. A data state metric for one or more wordlines of the memory device is determined. Responsive to determining that the data state metric exceeds a corresponding media management threshold value of the one or more adjusted media management threshold values, a media management operation is performed with respect to a block comprising the one or more wordlines.

The processing device causes a health scan to be performed on a set of memory units residing within one or more dies and updates, for each read sample taken during the health scan of a unit of memory, an assignment to a voltage offset bin of a plurality of voltage offset bins. The processing device tracks, by a memory data structure, the updated assignments to the plurality of voltage offset bins and generates, based on the memory data structure, an error rate distribution of the memory device. In response to determining that a trigger rate (TR) margin value associated with the error rate distribution does not satisfy a threshold value, the processing device causes a data associated with the unit of memory to be refreshed.

Abstract: The present disclosure configures a system component, such as memory sub-system controller, to perform empty page scan operations.
