MEMORY TRANSFER OF OBJECTS IN A DATA STORAGE DEVICE

摘要

Herein are data storage devices to transfer a data object between memory regions during a storage operation. These data storage devices include a host controller configured to identify an object stored in a host region of a memory system for writing to a storage media controlled by a drive controller. The host controller initiates a memory transfer operation to transfer an object from the host region of the memory system to a drive region of the memory system. The host controller transfers a storage command to the drive controller to write the object to the storage media. The drive controller may be configured to transfer an object from the drive region to the host region when reading the object.

1. A data storage device comprising:
a memory system, connected to a host controller and a drive controller, the memory system comprising a host region allocated to the host controller and a drive region allocated to the drive controller; the host controller configured to identify an object stored in the host region of the memory system for writing to a storage media controlled by the drive controller, initiate a memory transfer operation to transfer at least a portion of the object from the host region of the memory system to the drive region of the memory system, and transfer a storage command to the drive controller to write at least the portion of the object to the storage media; the drive controller configured to receive and process the storage command to write to the storage media at least the portion of the object in the drive region of the memory system to the storage media.
