  • POWER AWARE PROGRAMMABLE NEGATIVE BIT LINE CONTROL
    Publication number: 20200090736
    Abstract: A write driver includes a first write data driver, a second write driver, and a control circuit. The first (second) write data driver provides a true (complement) write data signal to an output thereof at a high voltage when a true (complement) data signal is in a first logic state, at a ground voltage when the true (complement) data signal is in a second logic state and a negative bit line enable signal is inactive, and at a voltage below the ground voltage when the true (complement) data signal is in the second logic state and the negative bit line enable signal is active. The control circuit provides the negative bit line enable signal in an active state when a power supply voltage is below a first threshold, and in an inactive state when the power supply voltage is above a second threshold higher than the first threshold.
