Abstract
A delay device for delaying the activation of a sensing indication signal includes a reference word-line, a reference word-line driver, and a comparator. The reference word-line driver is controlled by a strobe signal, and is connected to the reference word-line and a reference word-line voltage. Additionally, when so indicated by the strobe signal, the reference word-line driver provides the reference word-line voltage to the reference word-line. The comparator is connected to the reference word-line and to the reference word-line voltage and activates the sensing indication signal when the voltage on the reference word-line is at least equal to a predetermined function of the reference word-line voltage.
