  • Circuit and method for address transition detection
    Patent number: 8861303
    Abstract: A new address transition detection (ATD) circuit for use on an address bus having a plurality of address signal lines comprises a first circuit for each address signal line and a second circuit. The first circuit has a first input, a second input and an output. The first input is coupled to an address signal line. The second input is coupled to an ATD signal. The first circuit saves the current level of the first input in response to an ATD pulse on the ATD signal and generates a change signal at its output by comparing the current level and the saved level of the first input. The second circuit has an input and an output. The second circuit receives on its input the change signal from the first circuit. In response, the second circuit generates the ATD pulse on the ATD signal at its output.
