Abstract

During a program verify sensing operation, a tracking signal may be generated to match a sense amplifier signal. A data stream from a sequence generator may be held at a pass/hold logic until the tracking signal reaches a trip point. The data stream may be subsequently latched at a main latch with the sense amplifier signal.
