Claim 10:
11. A memory system, comprising:
a nonvolatile memory device including a plurality of word lines; and
a memory controller setting an adjusted target programming time so that a variation width of a writing speed of the memory system for a predetermined time satisfies a reference value, wherein:
the memory controller transmits an initial target programming time corresponding to a word line to be programmed to the nonvolatile memory device, and
when the memory controller transmits a program command for the word line to the nonvolatile memory device, the nonvolatile memory device confirms a programming time of the word line, and adjusts the initial target programming time to form the adjusted target programming time of the word line on the basis of the initial target programming time.
