ABSTRACT:
A voltage generator for use in a semiconductor memory device suitable for use as a backbias voltage generator, as an internal high voltage generator, or as an internal power voltage generator. The present invention includes: a rectifier for producing a dc voltage power by rectifying clock signals; an oscillator including an odd number of invertors connected in series, and with the output of the last invertor fed back to the first invertor so as to oscillate clock pulses; and one or more bypass circuit connected so as for the output of the first invertor to bypass one or more intermediate invertors, and connected and disconnected by a control switch.
