Abstract
A memory circuit for an inkjet print head having a plurality of memory cells switchably connected to a source and configured in an array, wherein at least one of the memory cells is a reference memory cell and at least one of the remaining cells are data memory cells, and at least one sense amplifier adapted to compare at least one of a current and voltage received from the reference memory cell with at least one of a current and voltage received from one of the data memory cells and generate an output based on the comparison.
