Abstract
Provided herein may be a storage device and a method of operating the storage device.

Claims17
A storage device comprising:
- a memory device including a plurality of memory blocks;
- and
- a memory controller configured to control the memory device to perform a background erase operation on at least one free block of the plurality of memory blocks based on information about a size of write data to be provided to the memory device.
A method of operating a memory controller configured to control a memory device including a plurality of memory blocks, the method comprising:
- obtaining information about a size of write data to be provided to the memory device;
- and
- instructing the memory device to perform a background erase operation on at least one free block of the plurality of memory blocks based on the information about the size of the write data.
A memory system comprising:
- a memory device including a plurality of memory blocks;
- and
- a controller configured to control, when accumulated size of data stored in the memory blocks becomes greater than storage capacity of a single memory block, the memory device to perform a background erase operation on one or more memory blocks storing invalid data among the memory blocks while the memory device is idle.
