Abstract: An example memory sub-system includes a memory device and a processing device, operatively coupled to the memory device. The processing device is configured to initiate a scan process on a plurality of block families of the memory device; responsive to determining, based on the scan process, that a first block family of the plurality of block families and a second block family of the plurality of block families meet a combining criterion, merge the first block family and the second block family; and responsive to determining that a terminating condition has been satisfied, terminate the scan process.

Abstract: One or more blocks at the memory device are programed. The one or more blocks are associated with a block family and with one or more dice of a die group. A voltage offset bin associated with the die group and the block family is determined based on a subset of dice of the die group. Metadata associated with the memory device is appended to include a record associating the die group and the block family with the voltage offset bin.

Abstract: A includes a memory device and a processing device, operatively coupled to the memory device. The processing device is to: initialize a block family associated with the memory device; initialize a timer at initialization of the block family; and aggregate temperature values received from sensor(s) of the memory device over time to generate an aggregate temperature. Responsive to programming a page residing on the memory device, the processing device associates the page with the block family. The processing device closes the block family in response to the aggregate temperature being greater than a first temperature value and the timer reaching a first time value. The processing device closes the block family in response to the aggregate temperature being less than or equal to the first temperature value and the timer reaching a second time value that is greater than the first time value.
