    摘要: A non-volatile semiconductor memory device includes a flip-flop circuit for holding write data in one of first and second states. A bit line is connected to the flip-flop circuit via a switching element, and a transistor changes the bit line. A non-volatile memory cell, connected to the bit line and having a MOS transistor structure, stores data when a threshold thereof is set in one of first and second threshold ranges, wherein at the time of a write mode the threshold of the memory cell is shifted from the first threshold range towards the second threshold range while the flip-flop circuit remains in the first state and the shift of the threshold is not effected while the flip-flop circuit remains in the second state, and at the time of a verify mode following the write mode the bit line is kept at a charge potential by the charging transistor while the threshold remains in the second threshold range. A data setting circuit connects one of first and second signal nodes of the flip-flop circuit to a predetermined potential when the bit line is at the charge potential in the verify mode, thereby setting the flip-flop circuit in the second state irrespective of the state prior to the verify mode.

    摘要: The first input terminal of a differential amplification type sense amplifier is connected to a first memory cell array and the second input terminal thereof is connected to a second memory cell array. Each of the first and second memory cell arrays is formed of a plurality of memory cells arranged in a matrix form. Each of the memory cells in the first memory cell array and a corresponding one of the memory cells in the second memory cell array are provided in the form of pair for each bit. Complementary data is programmed into the paired memory cells according to programming data. In the data readout operation, the potential of data read out from the paired memory cells is amplified by means of the differential amplification type sense amplifier. First and second loads are connected to the first and second input terminals of the differential amplification type sense amplifier. The mutual conductances of the first and second loads are controlled so as to set the potential difference between the potentials of data read out from the paired memory cells selected in the first and second memory cell arrays smaller in the verify mode than in the normal readout mode.

    摘要: For precisely determining a position of an electronic pen using ultrasonic, only a direct wave arriving first at a reception device is detected without being affected by a reflected wave of an ultrasonic signal to count a propagation time of the electronic pen.An infrared signal including a trigger signal indicative of transmission timing and data indicative of an M-sequence initial condition, and an ultrasonic signal made into an M-sequence are simultaneously sent from the electronic pen in each fixed transmission cycle. The reception device disposed at a predetermined position receives the infrared signal from the electronic pen to generate an M-sequence model waveform from M-sequence initial condition data that the infrared signal includes. The reception device further receives the ultrasonic signal from the electronic pen to calculate a value of correlation between the ultrasonic signal and the above-described M-sequence model waveform. Upon detecting a first peak of the calculated correlation value, the reception device calculates a propagation time of ultrasonic from the electronic pen from a time point of reception of the previously received trigger signal and a time point of detection of the detected correlation peak.

    摘要: To enable precise calculation of a propagation time of a direct wave which arrives fastest from an ultrasonic generation source without being affected by a reflected wave of an ultrasonic signal.A plurality of ultrasonic signals generated based on a plurality of M sequences different from each other are propagated from a transmission side to a reception side, whereby the reception side generates model waveforms of the plurality of M sequences, executes correlation processing between each model waveform and a waveform of each ultrasonic signal and detects a secondary peak of a correlation value which appears when both waveforms partly coincide with each other to determine an M sequence which generates a smallest secondary peak among secondary peaks detected by all the correlation processing as an optimum M sequence. The transmission side sends out an electromagnetic signal and an ultrasonic signal modulated by an optimum M sequence generated based on an initial condition of the optimum M sequence to the reception side. The reception side calculates a correlation value between the ultrasonic signal and a model waveform of the ultrasonic modulated by the optimum M sequence, detects a first primary peak of the calculated correlation value and calculates an ultrasonic propagation time from a time point of the reception of the electromagnetic signal and a time point of the detection of the primary peak.

    摘要: High-quality and high-speed electronic pen drawing performance is ensured without being affected by noise of an ultrasonic signal which is generated by an apparatus using ultrasonic such as a motion detector. In an ultrasonic receiver for use in ultrasonic propagation time measurement, an external environment noise is measured to first determine a frequency. Thereafter, centered around the frequency, a band elimination filter having a several kHz band is structured as software to again measure an external environment noise. This sequence is repeated until a signal intensity lowers below a predetermined value. When the signal intensity fails to lower below the predetermined value even after a predetermined number of repetitions of the sequence, a transmission output on the side of an electronic pen as an ultrasonic transmission source is increased or an ultrasonic oscillation frequency is changed.

    摘要: A memory cell array has a unit formed from one memory cell and two select transistors sandwiching the memory cell. One block has one control gate line. Memory cells connected to one control gate line form one page. A sense amplifier having a latch function is connected to a bit line. In a data change operation, data of memory cells of one page are read to the sense amplifiers. After data are superscribed on data in the sense amplifiers, and a page erase is performed, data in the sense amplifiers are programmed in the memory cells of one page. Superscription of data in the sense amplifiers allows a data change operation for byte data or page data.
