Abstract
An erasing method of a single-gate non-volatile memory is provided. The single-gate non-volatile memory has a single floating gate. The erasing method includes applying a voltage to the drain without applying to the gate to create and control an inversion layer. Therefore the required erasing voltage is reduced and the erasing speed is improved to avoid the over-erase problem.
