receiving, from a host device, an external read command to retrieve first information from a first location of a memory device;
executing a first internal read command to retrieve first metadata associated with the first information in the external read command from a second location of the memory device based at least in part on receiving the external read command from the host device, wherein the first information and the first metadata were stored in the memory device;
transferring the first metadata from the second location of the memory device to a buffer based at least in part on executing the first internal read command;
executing a second internal read command to retrieve the first information from the first location based at least in part on receiving the external read command and transferring the first metadata to the buffer; and
