ABSTRACT:
A pull-up circuit for a memory provides an additional natural transistor between a power supply and diode-connected transistors which reduces the voltage on bit sense lines sufficiently to allow selected column select transistors to turn on prior to a memory cell being enabled. Additional control circuitry further reduces the voltage to the diode-connected transistors when no memory cells have been selected to be enabled to compensate for the reduction in voltage drop across the natural transistor when no current is flowing through it.
