Publication number: 20100040122Abstract: Embodiments provide methods, systems, and apparatuses including combinatorial or reconfigurable circuitry having input/output (I/O) circuitry with an I/O terminal and an input buffer. The I/O terminal receives a receive signal at a receive signal level that was transmitted from another integrated circuit at a transmitted signal level which is either a first or a second different signal level. The input buffer compares the receive signal to one or more reference signals to generate an input signal corresponding to the transmitted signal level based at least in part on the result of the comparison, even if the receive signal is received at a third signal level in between the first and the second signal level.Type: ApplicationFiled: August 12, 2008Publication date: February 18, 2010Applicant: M2000 SA.Inventors: Jean Barbier, Olivier V.
