Abstract
One or more clock signals are used to control sense amplifier measurements. For example, multiple threshold voltage measurement types characterize the multiple clock signals, and selecting the appropriate clock signal selects the appropriate measurement type. In another example, multiple clock signals control multiple measurements of a particular location of nonvolatile memory, so that one of multiple clock signals is selected or the appropriate clock signal is generated to apply an appropriate threshold voltage window sensitivity.
