1. A memory system, comprising:
one or more memory devices; and
processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
determine positions of one or more translation groups in a queue associated with a garbage collection operation of a source block of memory cells of the one or more memory devices, wherein the one or more translation groups are associated with a plurality of pages of the source block;
identify a first set of valid pages of the plurality of pages as a first type associated with a first access frequency and a second set of valid pages of the plurality of pages as a second type associated with a second access frequency based at least in part on the positions of the one or more translation groups in the queue; and
transfer the first set of valid pages to a first destination block of memory cells of the one or more memory devices and the second set of valid pages to a second destination block of memory cells of the one or more memory devices.
