ABSTRACT:
An interface circuit between NULL Convention Logic and non-NULL convention memory includes: a first conversion circuit which converts NULL convention address signals to non-NULL address signals. A non-NULL convention memory circuit, e.g., a conventional binary memory, generates non-NULL data signals in response to the non-NULL address signals. A second conversion circuit converts the non-NULL data signals to NULL convention data signals. A timing circuit controls DATA and NULL wavefronts to and through the non-NULL memory.
