摘要： Operational stability of the nonvolatile memory in plural power supply voltage modes set up in advance corresponding to the power supply voltage level is realized. A nonvolatile memory is configured with a memory array, a charge pump, a distributor for selecting an output voltage of the charge pump, and a sequencer for controlling operation of the charge pump and the distributor. The nonvolatile memory is also provided with an analyzer which notifies the sequencer of a power supply voltage mode selectively specified among plural power supply voltage modes set up in advance corresponding to power supply voltage levels, and which detects mismatch between the power supply voltage mode notified to the sequencer and an actually supplied power supply voltage and limits the operation of the charge pump and the distributor with the use of the sequencer, based on the detection result. An operational stability of the nonvolatile memory is realized.

摘要： This invention is to reduce the number of memory gate drivers, while lessening the number of times of disturb occurrence in a memory array configuration that implements writing in small byte units. A memory array comprises a plurality of sub-arrays, MG transfers, SL drivers, and CG drivers. Each sub-array includes a plurality of memory gate lines, control gate lines, source lines, and bit lines. Memory cells are arranged in positions of intersections of these lines. The control gate lines, CG drivers, source lines, and SL drivers are common to the sub-arrays, whereas the memory gate lines and MG buffer circuits are provided for each sub-array. Thereby, the units in which data is written are decreased and adverse effects of disturb are reduced without increasing the circuit size of the memory array.

摘要： Erasing is performed with respect to a nonvolatile memory cell without causing depletion halfway therethrough. A control circuit for reversibly and variably controlling the threshold voltage of the nonvolatile memory cell by electrical erasing and writing controls an erase process of performing erasing to the plurality of nonvolatile memory cells assigned to one unit in an erase operation, a first write process of performing writing to the nonvolatile memory cell exceeding a pre-write-back level before a depletion level, and a second write process of performing writing to the nonvolatile memory cell exceeding a write-back level after the first write process. Since the occurrence of depletion is suppressed by successively performing the first write process with respect to the nonvolatile memory cells which may exceed the depletion level in the erase process, erasing can be performed to the nonvolatile memory cell without causing depletion halfway therethrough.

摘要： A light shutter device which has a plurality of light transmitting portions (light shutter elements) on a planar PLZT substrate. By applying voltages between a common electrode and individual electrodes to apply electric fields to the light shutter elements, the light shutter elements transmit and shut light individually. Suppose each of the individual electrodes faces the common electrode at a distance L and has a dimension W in a direction perpendicular to the direction of electric field, W/L>2. Suppose each of the individual electrodes has a dimension D in the direction of electric field, preferably D/L>0.5. Further, the individual electrodes are so placed that the distance between a side of one light shutter element which extends in a direction perpendicular to the direction of electric field and each of the individual electrodes which drive the other light shutter elements is not less than 5L.
