  • Apparatus and system for reading non-volatile memory with dual reference cells
    Patent number: 6665216
    Abstract: A system for reading data in a memory cell includes three comparators, each of which has two inputs. A first reference cell having a low reference voltage is coupled to one input of the first comparator. A second reference cell having a high reference voltage is coupled to one input of the second comparator. A memory cell having a memory cell voltage is coupled to the other input of the first and second comparators. One input of the third comparator is coupled to the first comparator's output signal, which includes a difference voltage between the memory cell voltage and the low reference voltage. The other input of the third comparator is coupled to the second comparator's output signal, which includes a difference voltage between the memory cell voltage and the high reference voltage. A method and apparatus for reading data in a memory cell also are described.
