Abstract
When applying a sensing voltage at one end of a word line of a non-volatile memory circuit, an initial kick, where the voltage is initially raised somewhat above its final desired voltage, is used. Using on-chip circuitry for the determination of the RC time constant of the word lines allows for this kick to be trimmed to the specifics of the circuit. To further improve settling times for read operations is NAND type architectures, when raising the voltage to the desired read level on a selected word line, a reverse kick, where the non-selected word line's voltage is dropped briefly, can be applied to neighboring non-selected word lines.
