Abstract
An apparatus is disclosed which comprises an improved voltage driver circuit. Commonly available voltage driver circuits are deficient for driving n-channel MOS RAMs due to insufficient peak voltage and extended rise time. The apparatus, without requiring an additional voltage power supply or modifications to the memory system environment, effectively increases an internal drive voltage which results in the desired performance characteristics for driver circuits.
