    摘要: A nonvolatile semiconductor memory device includes a memory cell, formed in a well in a substrate and having a source, a drain, a first gate and a second gate. A word line control circuit drives a word line connected to the second gate, a program data holding circuit holds program data, a programming voltage generator circuit applies a programming voltage onto a bit line connected to the drain, and a discrimination circuit verifies the program data. Programming is conducted by applying positive voltages to the second gate and drain, while injecting hot electrons generated in a channel portion in a vicinity of the drain when 0V is applied to the well and source to increase a threshold voltage. Verification is conducted by applying a verify voltage to the second gate, while applying a positive voltage to the drain and 0V to the well and source, thereby verifying whether the positive voltage applied is maintained or comes down to 0V, depending upon the threshold voltage, by means of the discrimination circuit.

    摘要: In a nonvolatile semiconductor memory device capable of the storage of multivalued data, fast writing can be realized with high reliability. In such a nonvolatile semiconductor memory device for storing multivalued information in one memory cell by setting a plurality of threshold voltages of data, writing of data having one threshold voltage that is the remotest to an erased state is performed prior to writing of the data having the other threshold voltages (write #1). Writing of the data having the other threshold voltages is then sequentially performed within groups of threshold voltages, starting from the nearer threshold voltage to the erased state within each group. When writing each of the data having the other threshold voltages, writing of the data is performed to a memory cell beginning with those groups having the remoter threshold voltages from the erased state.

    摘要: A picture reducing circuit 1 reduces a supplied original picture. A higher picture memory 2 stores an input higher picture. A predictive tap extracting circuit 3 extracts predictive taps from the higher picture stored in the higher picture memory 2 and outputs the extracted predictive taps to a mapping circuit 4, predictive coefficient generating circuit 5, and pixel value updating circuit 8. The mapping circuit 4 calculates a linear combination of predictive taps and predictive coefficients and obtains a predictive picture. The predictive picture is output to an error calculating circuit 6. The error calculating circuit 6 calculates an error (S/N ratio) between pixel value of the predictive picture and that of the original picture. A comparing and determining circuit 7 controls a non-linear processing circuit 9 corresponding to the difference of the errors. The non-linear processing circuit 9 adds or subtracts a predetermined value to/from the pixel value of each pixel of the updated higher picture corresponding to the variation amount of pixel value updated by the pixel value updating circuit 8.
