  • Patent number: 8937840
    Abstract: A digital voltage boost circuit, optionally working in parallel with an analog voltage regulator, periodically injects a constant amount of current each cycle into the bit line of a high density memory array to eliminate the bias voltage reduction which would otherwise occur. This results in a much faster recovery time and reduces the semiconductor real estate required. A pulse generator in the boost circuit generates one or more current modulation signals which control corresponding current supply devices in a current source. The boost circuit drives a constant amount of current to the bias voltage node each memory cycle.
