Abstract:
1. An operating method for a non-volatile memory, wherein the non-volatile memory is disposed on a silicon on insulation (SOI) substrate having a first conductive type doped region disposed in and electrically connected to a first conductive type silicon body layer, the non-volatile memory comprising a gate, a charge storage structure, a second conductive type drain region, and a second conductive type source region, wherein the first conductive type is P type, and the second conductive type is N type, wherein the first conductive type doped region and the second conductive type source region are disposed at the same lateral side of the gate and are juxtaposedly arranged along a longitudal direction of the gate, the operating method comprising: applying a first voltage to the gate, applying a second voltage to the second conductive type drain region, applying a third voltage to the second conductive type source, and applying a fourth voltage to the first conductive type doped region to inject electrons into the charge storage structure by channel hot electron injection, wherein the second voltage is greater than the third voltage, and the first voltage is greater than the fourth voltage.
