Abstract
A semiconductor memory device includes memory cells arranged at regions where word lines and bit lines cross each other; a randomizing and de-randomizing circuit configured to perform a first randomizing operation on data to be programmed to the memory cells, based on a seed value, so as to generate first randomized data; a data reading/writing circuit configured to perform a second randomizing operation on the first randomized data using a data inverting operation so as to generate second randomized data and program the second randomized data to the memory cells; and a control logic configured to control the randomizing and de-randomizing circuit and the data reading/writing circuit.
