APARATUS OF MULTI BIT PROGRAMMING FOR NON-VOLATILE MEMORY AND METHOD USING THE APARATUS

摘要

An apparatus of multi bit programming for non-volatile memory is provided to reduce error in programming while not requiring an additional semiconductor chip area. In an apparatus of multi bit programming for non-volatile memory, a multi-bit programming part unit(510) programs original data of multi-bit in the target memory cell in the non-volatile memory cell array multi-bit. A backup programming unit(520) selects the backup memory cell for each bit of original data, and programs each bit of original data in the selected backup memory cell. A data validation unit(530) compares data programmed in backup memory cells with data programmed in the target memory cell multi-bit, and verifies the multi-bit programming success.
