Abstract
A method and apparatus for transferring a signal from a high voltage, low current source to a word select line in an electrically erasable, programmable read-only memory wherein a control signal is generated which is incremented in magnitude over time, the control signal being used to control a signal path between the high voltage, low current source and the desired word select line, such that the signal path is established whenever the difference between the control signal and the signal level on the word select line exceeds a predetermined threshold level, whereby the signal level on the desired word select line increases gradually over time to the high voltage level.
