ABSTRACT:
A circuit is disclosed for generating a two-stage boot signal, the first stage being a transition from a low voltage to a high voltage, and the second stage being a transition from the high voltage to an increased high voltage. The first stage operates to read the contents from a memory cell, and the second stage operates to restore the contents of the access memory cell. A capacitor (102) is charged with a voltage to boost the output (122) of the circuit (52) in order to produce the increased high voltage. However, the lower plate (100) of the capacitor (102) is effectively disconnected from the circuit during the transition from a low to high voltage in order to provide a fast transition period.
