Abstract
When an array VT test mode is entered, a predetermined wordline voltage is generated by a wordline voltage supply and supplied to at least one decoder circuit and a voltage control logic circuit. The voltage control logic circuit generates a predetermined control voltage that is directed to the decoder circuits. The predetermined control voltage activates the decoder circuits. A particular decoder circuit is electrically selected to decode at least one respective wordline and transfer the predetermined wordline voltage to the respective wordline. The activated decoder circuits that are not electrically selected are not forward-biased.
