Abstract
Disclosed is a storage device which includes a memory device including a plurality of nonvolatile memory blocks, and a memory controller configured to control the memory device. The memory controller is configured to determine continuity of a first physical address of first user data among user data stored in the memory device in a read operation unit of the memory device in response to a sequential read command for the user data, and store the first user data whose first physical address is discontinuous at a second physical address continuous in the read operation unit of the memory device.
Claims20
A storage device comprising:
- a memory device including a plurality of nonvolatile memory blocks;
- and
- a memory controller configured to control the memory device,
- wherein the memory controller is configured to:
- determine continuity of a first physical address of first user data among user data stored in the memory device in a read operation unit of the memory device in response to a sequential read command for the user data;
- and
- store the first user data whose first physical address is discontinuous at a second physical address continuous in the read operation unit of the memory device.
A storage device comprising:
- a memory device including a plurality of nonvolatile memory blocks;
- and
- a memory controller configured to control the memory device,
- wherein the memory controller is configured to:
- receive a write command including a first logical address and first user data;
- determine continuity of a second logical address of second user data and continuity of a second physical address of the second user data in a read operation unit of the memory device;
- and
- based on the second logical address and the second physical address being continuous, store pieces of user data other than user data stored at a first physical address from among pieces of second user data stored at the second physical address and the first user data as a third physical address as third data,
- wherein the third physical address is continuous in the read operation unit of the memory device,
- wherein the first logical address is included in the second logical address, and
- wherein the first logical address is mapped to the first physical address.
An operating method of a storage device, the method comprising:
- data;
- determining, at the memory controller, continuity of a first physical address of first user data among the user data stored in a memory device in a read operation unit of the memory device;
- and
- storing, at the memory controller, the first user data, the first physical address of which is discontinuous, at a second physical address continuous in the read operation unit of the memory device.
