ABSTRACT:
Methods of programming NEW data into unprogrammed bits of a group of memory cells is provided. The method applies an interactive programming algorithm that individually verifies and programs the NEW data, reference (REF) data, and existing or OLD data. OLD data is separately verified to a compensated program verify level from that of the NEW data to improve memory reliability and insure minimal uniform stress levels to the array. The improved programming algorithm prevents older data from being needlessly refreshed, thus mitigating stress to the cells that eventually causes the data areas to decay at different rates and become prematurely unreliable.
