Abstract: A region of a memory component is determined to include a type of memory. A frequency to perform an operation on the region of the memory component is determined based on the type of memory. The operation is performed on a memory cell at the region of the memory component at the determined frequency to transition the memory cell from a state associated with an increased error rate for data stored at the memory cell to another state associated with a decreased error rate for the data stored at the memory cell.

Abstract: A processing device in a memory system determines that a first metric of a first memory unit on a first plane of a memory device satisfies a first threshold criterion. The processing device further determines whether a second metric of a second memory unit on a second plane of the memory device satisfies a second threshold criterion, wherein the second block is associated with the first block, and wherein the second threshold criterion is lower than the first threshold criterion. Responsive to the second metric satisfying the second threshold criterion, the processing device performs a multi-plane data integrity operation to determine a first reliability statistic for the first memory unit and a second reliability statistic for the second memory unit in parallel.

Abstract: A first data block of multiple data blocks is identified in a first portion of the memory component, the first data block being identified based on a read count associated with the first data block satisfies a first threshold criterion. A determination is made as to whether a second portion of the memory component has an amount of unused storage to store data stored at the first data block, wherein the second portion of the memory component is associated with a lower read latency than the first portion. In response to determining that the second portion of the memory component has the amount of unused storage to store the data stored at the first data block, data stored at the first data block in the first portion of the memory component is relocated to a second data block in the second portion of the memory component. An error rate is evaluated on each word line in the first data block.

Abstract: An indication of an initialization of power to a memory component can be received. In response to receiving the indication of the initialization, a last written page of a data block of the memory component can be identified. The last written page is associated with a status indicator. A determination is made of whether the status indicator can be read. Responsive to determining that the status indicator cannot be read, it can be determined that programming of data to the data block of the memory component did not complete based on a prior loss of power to the memory component.
