A method of operating a non-volatile memory comprising a substrate, a gate, a charge-trapping layer, a source region and a drain region is provided. The charge-trapping layer close to the source region is an auxiliary charge region and the charge-trapping layer close to the drain region is a data storage region. Before prosecuting the operation, electrons have been injected into the auxiliary charge region. When prosecuting the programming operation, a first voltage is applied to the gate, a second voltage is applied to the source region, a third voltage is applied to the drain region and a fourth voltage is applied to the substrate. The first voltage is bigger than the fourth voltage, the third voltage is bigger than the second voltage, and the second voltage is bigger than the fourth voltage to initiate a channel initiated secondary hot electron injection to inject electrons into the data storage region.
