A circuit comprises a first driver, a second driver, and a remote sense amplifier. The first driver is configured to generate a first data signal on a first data line. The second driver is configured to generate a control signal on a control signal line. An RC delay of the control signal line is less than an RC delay of the first data line. The remote sense amplifier is configured to receive the first data signal, a second data signal on a second data line, and the control signal. The control signal line is configured for the control signal to enable the remote sense amplifier to amplify the voltage difference between the first data signal and the second data signal at inputs of the remote sense amplifier, if the voltage difference reaches a predetermined value.
