ABSTRACT Apparatus and method for generating substrate bias for the refresh apparatus of volatile memory elements associated with data processing units. A refresh oscillator in the refresh apparatus is utilized to drive a chopper circuit or high level driver in combination with a rectifier network for ob- taining raw negative voltage. The raw voltage is filtered and adjusted to the correct value on the metal oxide semiconductor (MOS) memory board and distributed to each random access memory (RAM).
