Method of writing data in storage device using write throttling and storage device performing the same

A storage device comprising:

• a nonvolatile memory;
• and
• a storage controller configured to:
• receive write data from a host device;
• monitor an operating temperature of the storage device;
• generate a plurality of write data blocks respectively corresponding to a plurality of storage regions of the nonvolatile memory based on the write data;
• and
• based on the operating temperature, perform a write operation on P write data blocks among the plurality of write data blocks by transmitting a write command to P storage regions among the plurality of storage regions and skipping the write operation on X write data blocks among the plurality of write data blocks by skipping an operation of transmitting the write command to X storage regions among the plurality of storage regions,
• wherein P and X are natural numbers.

A method of writing data in a storage device, the method comprising:

• receiving write data from a host device;
• monitoring an operating temperature of the storage device;
• dividing the write data into N sub-data, where N is a natural number greater than or equal to two;
• obtaining a plurality of write data blocks respectively corresponding to a plurality of storage regions of the storage device by encoding the N sub-data, the plurality of write data blocks comprising N data blocks and K parity blocks, where K is a natural number;
• based on the operating temperature being less than or equal to a first reference temperature, performing a write operation on each of the plurality of write data blocks by transmitting a write command to each of the plurality of storage regions;
• based on the operating temperature being higher than the first reference temperature, skipping the write operation on X write data blocks among the plurality of write data blocks and performing the write operation on only P write data blocks among the plurality of write data blocks, where X and P are natural numbers and X is less than or equal to K;
• and
• after skipping the write operation on the X write data blocks, based on a write completion request being received from the host device, the storage device being in an idle state, or the operating temperature becoming lower than a second reference temperature lower than the first reference temperature, additionally performing a subsequent write operation on the X write data blocks.
