  • Reference circuit for integrated memory arrays having virtual ground connections
    Patent number: 4868790
    Abstract: A reference-column circuit for supplying a reference voltage to be used in sensing programming status of read-only-memory cells in a memory array having virtual-ground circuit connections is disclosed. The reference-column circuit includes an adjacent non-programmed memory cell having a common terminal with an identical non-programmed memory cell of prior-art circuitry. The additional memory cell and associated grounding circuit provide a compensating component of reference voltage to the input of a sense amplifier, the compensating component acting to eliminate a source of possible errors in sense amplifier transmission caused by non-programmed adjacent memory cells in the memory array.
