1. An apparatus, comprising:
one or more memory devices; and
a controller coupled with the one or more memory devices and configured to cause the apparatus to:
initiate a media management operation to transfer first data of a first type from a first block of a first memory device of the one or more memory devices to a second block of the first memory device and to transfer second data of a second type from the first block of the first memory device to the second block of the first memory device, wherein the first type corresponds to critical data associated with a host system and the second type corresponds to non-critical data associated with the host system;
write, to transfer the first data as part of the media management operation and based at least in part on the first data being of the first type that corresponds to the critical data, the first data to a first set of memory cells of the second block coupled with a first set of word lines of the second block, the first set of word lines excluding word lines having a bit error rate that satisfies a threshold; and
write, to transfer the second data as part of the media management operation and based at least in part on the second data being of the second type that corresponds to the non-critical data, the second data to a second set of memory cells of the second block coupled with a second set of word lines of the second block, the second set of word lines comprising one or more word lines having the bit error rate that satisfies the threshold.
