Abstract
A circuit to restrain the rise time of a programming pulse generated in an electrically alterable read-only semiconductor memory in which excessively sudden changes in the pulse are capacitively coupled, through active devices that can be built on the chip, to a grounding switch device so as to periodically drain away the control signal used to create the pulse.
