Patent ID: 7296104

Claim:
A method comprising: performing a plurality of communications over a plurality of signal lines coupled between a transmitter and a receiver according to different parameters; determining, for each of the plurality of signal lines, whether a correct data value is received by the receiver for each of the plurality of communications; storing data transmission results according to each of the parameters for which transmissions are conducted in a storage mechanism, wherein the data transmission results are indicative of whether correct data values were received for the plurality of communications, and wherein the storage mechanism includes, for each of the plurality of signal lines, a table having a plurality of rows each corresponding to a first one of the different parameters and a plurality of columns each corresponding to a second one of the different parameters; and selecting designated parameters from the table corresponding to each of the plurality of signal lines for subsequent communications between the transmitter and the receiver, wherein the first one of the different parameters is a different sampling voltage threshold level.
