1. A method, comprising:
transmitting, from a host device to a memory device comprising a plurality of addresses, a request for information associated with access operation occurrence at the memory device;
receiving, at the host device based on transmitting the request, respective values of a plurality of fields of a register of the memory device, wherein a respective value of each field of the plurality of fields includes a count of a respective quantity of access operations of a respective set of multiple addresses of the plurality of addresses, wherein the plurality of fields includes a subset of multiple fields that is associated with a same address of the plurality of addresses, and wherein each field of the subset of multiple fields includes a count of a quantity of access operations of the same address of the plurality of addresses; and
performing one or more data allocation operations based on a value of at least one field of the plurality of fields of the register of the memory device.
