Abstract
A method of Chisel programming in non-volatile memory by source bias. Whereby when reading and/or programming operations are executed, a body reading voltage and a body programming voltage are used. The method is comprised of changing the body programming voltage to reduce the difference between the changed body programming voltage and the body reading voltage and then running the programming operation utilizing the changed body programming voltage. Advantages include: elimination of the negative effects of parasitic capacitors in memory cells, simplification of bias circuit design, enhanced device reliability, and reduced disturbance.
