Title: Semiconductor memory device
IPC: H01L29/792
Filed: 1992-03-17
Abstract: PURPOSE:To realize voltage reduction and efficiency improvement of writing and erasing of a nonvolatile storage transistor. CONSTITUTION:A storage transistor 3 being an EEPROM is arranged on the upper surface of a PN junction type blue light emitting diode 1, via a translucent insulating film 2. When the light emitting diode 1 is made to emit at the time of writing and erasing data, the emitted light passes through the translucent insulating film 2, and a channel region 21b is irradiated with the light. As a result, electrons and holes in the channel region 21b are optically excitated. The optically excited electrons or holes pass a first insulating film 22, and are trapped in a second insulating film 23. That is, the injection of electrons and holes are energized, so that low voltage driving is enabled. When an ultraviolet radiation type diode is used as the light emitting diode 1, erasing is possible only by the light emission of the light emitting diode.

Moreover, an internal FP signal generated by frequency-dividing an output of a VCX06 by a horizontal counter 8 (480 counts) and a vertical counter 9 (1125 counts) is inputted to the other input of the out of synchronization detection circuit 11. An output of the phase error detection circuit 3 is converted into an analog signal by a D/A converter 5 via a filter 4 and the converted signal is inputted to a control terminal of a VCXO6. A phase synchronization loop is formed by controlling an oscillating frequency of the VCXO 6 with a phase error output.
