Abstract
A system and method for preserving an error margin for a non-volatile memory that includes a memory cell, a reference cell coupled to a reference current mirror configured to mirror current through the reference cell. The system comprises a memory current mirror coupled to the memory cell and configured to mirror current through the memory cell. A sense amplifier has a first and a second input. The first input is coupled to the reference current mirror and the second input is coupled to the memory current mirror. The sense amplifier is configured to compare a voltage across the memory cell with a voltage across the reference cell.
