Abstract: Methods, systems, and devices for predictive media management for read disturb are described. A read disturbance manager can monitor a bit error rate for a block of a memory die. The read disturbance manager can detect that a degradation of the bit error rate satisfies a degradation threshold specific to the memory die. In some cases, the read disturbance manager can perform a write operation to write data from the block of the memory die to a second block of the memory die based on detecting that the degradation of the bit error rate satisfies the degradation threshold.

Abstract: A health check manager may detect a trigger for a capacitor health check for a memory sub-system. The health check manager may determine a number of write commands in a set of one or more pending commands for a memory die of the memory sub-system and set a start time for the capacitor health check based on the number of write commands in the set of one or more pending commands. In some cases, the health check manager may perform the capacitor health check in accordance with the start time.
