Abstract
Namespace planning of non-volatile memory that takes advantage of multi-channel accessing and considers multi-channel properties is provided. A data storage device includes a non-volatile memory and a controller. The controller accesses the non-volatile memory through multiple channels. When performing namespace planning on the non-volatile memory, the controller makes each assigned channel correspond to just one namespace.
Claims8
A data storage device, comprising:
- a non-volatile memory;
- and
- a controller, accessing the non-volatile memory through multiple channels, wherein:
- when performing namespace planning on the non-volatile memory, the controller makes each assigned channel correspond to just one namespace;
- when another namespace is requested to be created, a namespace originally existing in the non-volatile memory is de-attached to be planned by the controller again;
- and
- the controller moves data from a de-attached space to a newly-planned space.
