A method for measuring a write current of a semiconductor memory device includes the steps of: programming initial data into memory cells which are to be programmed substantially at the same time; determining whether the memory cells are programmed into the same state or not; inputting test data when the memory cells are programmed into the same state; setting write current paths of the memory cells by comparing the initial data and the test data; and measuring a write current consumed when the test data are programmed into the memory cells.
