Method and system for bi-directional voltage regulation detection

摘要

The present invention discloses a method and system of performing bi-directional voltage detection for a regulated voltage supply output in a memory device during a program verify operation. In the preferred embodiment, a voltage regulator is used to generate the regulated voltage supply output. The regulated voltage supply output is directed to a bi-directional voltage regulation detector and a transfer circuit. During operation, an output signal is generated with the bi-directional voltage regulation detector when the regulated voltage supply output is within a predetermined voltage range. If the regulated voltage supply output is within the predetermined voltage range, the regulated voltage supply output is passed to at least one wordline with the transfer circuit once the output signal is received by the transfer circuit from the bi-directional voltage regulation detector.
