摘要:
An apparatus and method for wordline voltage compensation in integrated memories is provided, where the apparatus includes an array threshold voltage (“VT”) monitor, a wordline on voltage (“Vpp”) generator in signal communication with the threshold voltage monitor for providing a wordline on voltage responsive to a change in the monitored array threshold voltage, and a wordline off voltage (“VWLL”) generator in signal communication with the threshold voltage monitor for providing a wordline off voltage responsive to a change in the monitored array threshold voltage; and where the corresponding method for compensating each of a wordline on signal and a wordline off signal in correspondence with an array threshold signal includes monitoring an array threshold signal, generating a wordline on signal responsive to the monitored array threshold signal, and generating a wordline off signal responsive to the monitored array threshold signal.
