Abstract

A system including a memory architecture is described. In one embodiment, the memory architecture includes an array of non-volatile memory cells, a first independently controlled voltage generation circuit, a plurality of register bits to store programmable values used by the independently controlled voltage generation circuit and a control circuit coupled to the first independently controlled voltage generation circuit. The first independently controlled voltage generation circuit is coupled to supply a positive voltage to the array during program and erase operations so that a magnitude of the positive voltage is applied across a storage node of an accessed memory cell of the array. The plurality of register bits to store programmable values used by the independently controlled voltage generation circuit to control the magnitude of the positive voltage. The control circuit controls a duration of the positive voltage. Other embodiments are also described.
