摘要： Disclosed is a method for refreshing voltages in a non volatile memory during a standby mode. The method comprises generating a first node voltage and a second node voltage through a resistance ladder, storing the voltages in a pair of capacitors, comparing the voltages by a comparator, generating an output electrical signal by the comparator upon comparing the voltages, latching the output electrical signal by a flip flop, generating an electrical refresh pulse by a refresh pulse generator upon receiving the output electrical signal from the flip flop, the electrical refresh pulse being supplied to a refresh node of a plurality of refresh nodes in the non volatile memory and generating an electrical sample pulse by a sample pulse generator, the electrical sample pulse along with the electrical refresh pulse setting the flip flop, thereby causing the flip flop to latch a new output electrical signal.
