Data storage device and method of writing data in the same

摘要

A method is provided for writing data in a storage device, including a nonvolatile memory. The method includes receiving a pre-write command including a logical address and size information of write data, performing a pre-operation for optimization of a write operation based on the pre-write command, and writing the write data in the nonvolatile memory after the pre-operation is completed.

1. A method of writing data in a storage device including a nonvolatile memory, the method comprising:
receiving a pre-write command for providing information associated with write data, the pre-write command including a logical address and size information of the write data; determining whether the received pre-write command contains an error; when it is determined that the received pre-write command does not contain an error, performing a pre-operation for optimization of a write operation based on the received pre-write command, the write operation being for writing the write data; and writing the write data corresponding to the received pre-write command in the nonvolatile memory after the pre-operation is completed, wherein performing the pre-operation comprises:
detecting a write pattern of the write data based on the received pre-write command;determining whether the write data is partial data based on the received pre-write command;checking validity of pages of memory of the nonvolatile memory based on the received pre-write command; andallocating the memory for the write data based on at least one of the detected write pattern, the partial data determination result, and the validity checking result.
