Implementations described herein relate to selective data map unit access. A memory device may receive a request from a host device to access a resource associated with a data map unit. The memory device may identify whether the data map unit is in a locked state or an unlocked state. The data map unit may be in the locked state when another host device currently has exclusive access to the resource or may be in the unlocked state when no other host device currently has exclusive access to the resource. The memory device may selectively grant the host device exclusive access to the resource based on identifying whether the data map unit is in the locked state or the unlocked state.
