Abstract
A method of compensating charge loss and source line bias in programing of non-volatile memory device including the steps of reading a previous program page with a low reference voltage to make an original previous program pattern, merging the original previous program pattern and a current program pattern to make a merged program pattern, reading the previous program page with a high reference voltage to make a verified previous program pattern, and merging the verified previous program pattern and the merged program pattern to make a compensated current program pattern.
