Abstract:
The present invention describes a uniform program method and a uniform erase method of a charge trapping memory by employing a substrate transient hot electron technique for programming, and a substrate transient hot hole technique for erasing, which emulate an FN tunneling method for NAND memory operation. The methods of the present invention are applicable to a wide variety of charge trapping memories including n-channel or p-channel SONOS types of memories and floating gate (FG) type memories. the programming of the charge trapping memory is conducted using a substrate transient hot electron injection in which a body bias voltage Vb has a short pulse width and a gate bias voltage Vg has a pulse width that is sufficient to move electrons from a channel region to a charge trapping structure.
