US Patent 7948802 Sensing memory cells

The present disclosure includes methods, devices, modules, and systems for operating memory cells. One method embodiment includes applying a ramping voltage to a control gate of a memory cell and to an analog-to-digital converter (ADC). The aforementioned embodiment of a method also includes detecting an output of the ADC at least partially in response to when the ramping voltage causes the memory cell to trip sense circuitry.
