Abstract
A storage device is provided. The storage device includes a memory device including a memory cell array configured to store metadata and main data and a storage controller configured to access the memory device and control the memory device, wherein the storage controller is configured to read data from the memory device at a speed adaptively varying to a first read speed or a second read speed according to a state of the memory device, the second read speed being faster than the first read speed.
Claims21
A storage device comprising:
- a memory device including a memory cell array configured to store metadata and main data;
- and
- a storage controller configured to access the memory device and control the memory device,
- wherein the storage controller is configured to read data from the memory device at a speed adaptively varying to a first read speed or a second read speed according to a state of the memory device, the second read speed being faster than the first read speed.
A storage device comprising:
- a memory device including a single-level cell area and a multi-level cell area;
- and
- a storage controller configured to adaptively vary a gear level for reading data stored in the single-level cell area according to a state of the memory device.
An operating method of a storage device, comprising:
- setting a read speed at a first gear level;
