    Abstract: A memory device, a memory system, and a method thereof are provided. In the method, an N-th programming pulse is applied to a word line coupled to memory cells of the memory device each with a target programming state being an i-th programming state. A first sub-verification and an M-th second sub-verification are performed on the memory cells to obtain a first sub-result and an M-th second sub-result, respectively. Based on the M-th second sub-result, a subset of the memory cells is determined to be programmed with an (N+1)-th programming pulse. Then, the (N+1)-th programming pulse is applied to the word line. After applying the (N+1)-th programming pulse to the word line, the memory cells are determined to be successfully programmed to the i-th programming state based on the first sub-result indicating that a number of failed bits in the first sub-verification is less than a first preset value.
