Title: Nonvolatile semiconductor device
Inventor: MARUYAMA AKIRA
IPC: G11C17/00
Filed: 1992-11-09
Abstract: PURPOSE:To relieve an excessively erased memory transistor in a nonvolatile semiconductor device, especially a flashing (batch erasing type) EPROM. CONSTITUTION:After erasing operation, by making a source line a GND level, bit lines BL1, BL2 an open level and word lines WL1, WL2 a high voltage level, electrons are injected into a floating gate electrode by means of a tunnelling current so as to perform writing. By increasing the threshold potential of an excessively erased memory transistor by writing, the excessive erasing is relieved. Consequently, erasing in parallel with the verifying operation for preventing the excessive erasing is not necessary. For example, since the erasing operation so as to decrease enough the threshold potential is executed once, then writing operation after erasing is performed and the erasing operation is completed, verifying operation is simplified.

Abstract: PURPOSE:To enable a non-contact type detection of acceleration with a high reliability along with a simplified construction, a smaller size and a lighter weight, by holding a magnetic spherical body positioned in a ferromagnetic fluid in a closed container at the center of the container with magnet couples when no acceleration is applied. CONSTITUTION:A magnetic spherical body 3 is positioned floating in a ferromagnetic fluid 2 sealed into a closed container 1 made of a non-magnetic material. Coil assemblies 4a and 4b comprising a detection coil and an excitation coil are arranged on the center axis of the closed container 1 and magnet couples 5a and 5b are arranged on the center axis orthogonal thereto. When no acceleration is applied, the magnetic spherical body 3 is held at the center of the closed container 1 with the action of a magnetic force of the magnet couples 5a and 5b and the action of a buoyance from the ferromagnetic fluid 2. Then, for example, when acceleration is applied to the right, the magnetic spherical body 3 is displaced to the left to reduce magnetic permeability with a decrease in the density of the left ferromagnetic fluid 2 so that the magnetic resistance of a magnetic circuit of the left coil assembly 4b increases to generate a differential output between the coil assemblies 4a and 4b. The size of the acceleration can be determined from the differential output.
