    摘要: A method for programming an MLC flash memory device minimizes interference between adjacent cells during a program operation, such that threshold voltage distribution becomes narrow and uniform. According to the method, an auxiliary program operation is performed on memory cells to be programmed, such that a majority of the memory cells have a positive threshold voltage. An LSB of a particular memory cell is programmed to a predetermined level, and data of the programmed LSB is sensed. An MSB of the particular memory cell is programmed to a predetermined level according to the sensed data of the LSB.
