An electrically erasable programmable read-only memory receives a single supply voltage and generates a first voltage higher than both the supply voltage and the ground voltage, a second voltage lower than both the supply voltage and the ground voltage. Each memory cell in the memory has a nonvolatile storage transistor with a floating gate. To erase the memory cell, the first voltage is applied on a first side of the floating gate and the second voltage is on a second, opposite side of the floating gate. To program the memory cell, the second voltage is applied on the first side of the floating gate, and the first voltage is applied on the second side of the floating gate.

A picture display method and apparatus in which a light source is lengthened in service life and optimum color reproduction is realized, while the light utilization efficiency is improved to reduce the power consumption and the size of the apparatus. The red, green and blue illuminating light beams radiated from the light-emitting diodes 12R, 12G and 12R, are illuminated via relay lenses and field lenses on picture display light valves 11R, 11G and 11B and spatially modulated in intensity so as to be synthesized by a synthesis prism 10 and so as to be projected to an enlarged scale on a screen 17. The profile of the light radiating portions of the light-emitting diodes 12R, 12G and 12B are set so as to be the same or similar to the profile of a picture display area of each of the picture display light valves 11R, 11G and 11B in order that the profile of the light beam illuminated on the picture display area will be in keeping with the profile of the picture display area.

The present invention relates to a digital data processing apparatus for transferring digital data which is output from a disc reproduction section (15.sub.1) to a buffer memory (18)-equipped host processing section (13) and for making processing. By detecting a shift in frequency of an operation clock on the basis of an output of the disc reproduction section (15.sub.1) and varying the frequency of the operation clock of the host processing section (13) in accordance with a result of that detection, it is possible to prevent the memory (18) from being placed in an over- or an underflowed state and to perform a normal data reproduction.

A voltage level detecting circuit includes a resistance voltage divider, a level converter and an MOS driver arranged such that the detection characteristics are immune to temperature variations. The voltage divider has two resistive elements serially connected to each other to produce a divided voltage. The two resistive elements have different resistance variations to temperature change. The level converter has a threshold voltage and converts a divided voltage which is more than the threshold voltage from the voltage divider into a binary signal. The MOS driver produces a control signal on receipt of a binary signal from the level converter.
