摘要:
A method of manufacturing a luminous sheet according to the present invention enables a planar display unit radiating fluorescence upon irradiation of ultraviolet rays to be easily offered. A ability of radiating fluorescence is also increased. To this end, an ultraviolet-excited luminous material is applied and dried over a film-like base sheet 10 to form a light emitting layer 20, and a resin solution is applied and dried over an upper surface of the light-emitting layer to form a back layer 40. After thus forming the light-emitting layer 20 and the back layer 40 into a one-piece body, the base sheet 10 is peeled off from the light-emitting layer 20. The specific gravity of the fluorescent material is selected to be three times or more the specific gravity of the resin solution used for forming the ultraviolet-excited luminous material.

A nonvolatile semiconductor memory device comprises a random access memory (RAM) and an electrically programmable and erasable read only memory (EEPROM). Since a capacitance (106) is formed between a control gate (103) and a drain (102) of a memory transistor, and a source of the memory transistor is rendered to be floating in the RAM write and read operation and in the EEPROM write operation and is supplied with a finite potential in EEPROM read operation, the operation of nonvolatile memory is achieved. A sense amplifier (15, 16) is amplified the potential difference between a bit line (BL) and a control gate line (CGL) is both memory operation and latches the input data in both write operation, such that the potential of the BL and the CGL are determined low or high potential. Besides in the EEPROM write operation, after latching the input data in the sense amplifier, a nonvolatile program is started such that a BL or a CGL is pumped up to program voltage (15-20 V). In the EEPROM read operation, a BL and a CGL are pre-changed in a different potential (BL CGL). After that, the sense amplifier is activated and the EEPROM data is read out.

摘要:
In a flash memory, after an initial write operation ends, each bit line associated with a memory cell subjected to a write is precharged and each bit line associated with a memory cell that is not subjected to the write is discharged and verified to detect a memory cell low in threshold voltage and a memory cell thus detected is subjected to an additional write. The verification can be verified without being affected by a current flowing through the memory cell that is not subjected to the write. All memory cells can have their respective threshold voltages set accurately.
