a circuit for sensing a difference in voltage on a pair of dual signal lines comprising a first signal line and a second signal line complementary to the first signal line, comprising: a pair of cross-coupled inverters arranged between the first and the second signal lines, each inverter having a pull-up transistor and a pull-down transistor, the sources of the pull-up transistors or of the pull-down transistors being respectively connected to a first and a second pull voltage signals, decode transistor having source and drain terminals respectively coupled to one of the first and second signal lines and a gate controlled by a decoding control signal, whereby when the decode transistor is turned on by the decoding control signal, a short circuit is established between the first and the second signal lines through which current flows from one of the first and second pull voltage signals, thereby generating a disturb in between the first and the second pull voltage signals. |
