  • Patent number: 10643695
    Abstract: A sense amplifier for a memory circuit that can sense into the deep negative voltage threshold region is described. A selected memory cell is sensed by discharging a source line through the memory cell into the bit line and sense amplifier. While discharging the source line through the memory cell into the sense amplifier, a voltage level on the discharge path is used to set the conductivity of a discharge transistor to a level corresponding to the conductivity of the selected memory cell. A sense node is then discharged through the discharge transistor. By allowing the sense amplifier to bias a memory cell being sensed to a selected one of multiple bias levels during a sensing operation, multiple target data states can be concurrently program verified, leading to higher performance when writing data.
