Disclosed herein is vibration motor. The vibration motor includes a bearing rotatably fitted over a support shaft which is installed to be perpendicular to a base. A hub is coupled to the bearing, with an eccentric member provided on the edge of the hub. A coil is mounted to the hub to form an electric field. A magnet having 2n poles is mounted on the base, and rotates the hub using electromagnetic force between the magnet and the coil. A detent magnet is mounted to the hub and stops the coil in the middle between the poles of the magnet.

A vibration actuator excites a mass member by interaction between an electric field of a vibration coil provided in an inner space of a case and a magnetic field of a magnetic field unit disposed corresponding to the vibration coil. The vibration actuator has an elastic wire having a wire body fixed to the outer surface of the mass member and elastic ends fixed to the inner surface of the case. The elastic wire is connected between the case and the mass member for elastically supporting mass member.

Erasure methods for a nonvolatile memory cell that includes a gate electrode on a substrate, source and drain regions in the substrate at respective sides of the gate electrode, and a charge storage layer interposed between the gate electrode and the substrate. A nonzero first voltage is applied to the source region starting at a first time. While continuing to apply the first nonzero voltage to the source region, a second voltage having an opposite polarity to the first voltage is applied to the gate electrode starting at a second time later than the first time. The second voltage may increase in magnitude, e.g., stepwise, linearly and/or along a curve, after the second time.
