Abstract: Implementations described herein relate to a two-stage emergency data storing operation. In some implementations, a memory device may detect a power loss notification signal that indicates a power loss condition of the memory device. The memory device may read a mode register bit of the memory device that indicates to perform a data storing operation that includes a first data storing stage and a second data storing stage. The first data storing stage may include storing data associated with the memory device prior to the memory device experiencing a power loss, and the second data storing stage may include storing data and metadata associated with the memory device prior to the memory device experiencing the power loss. The memory device may initiate the data storing operation and may selectively acknowledge the power loss condition based on completing the first data storing stage or the second data storing stage.

Abstract: 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.
