Nonvolatile, integrated metal-oxide semiconductor random access memory systems utilizing integrated floating gate circuit elements, and integrated means for the generation and control of high voltages in the provision of self-contained, nonvolatile electrically-alterable static RAM circuit systems.

Nonvolatile static random access memory system

Integrated circuit system for generating a rise-time regulated and level controlled high voltage pulse utilizing a plurality of diode-connected stages driven by capacitively coupled low voltage clocks. The maximum output voltage may be controlled by a gated diode reference device, which provides a reference voltage independent of power supply voltage. A feedback circuit may be provided which controls the high voltage rise time by modulating the effective low voltage clock amplitude driving the high voltage generator. A MOS logic level interface circuit may also be provided for sensing achievement of the predetermined high voltage level.
