Samsung patents chip method to test data link quality
Samsung describes a method where a chip measures the clarity of a data signal received from another chip. It stores this quality data and shares it with the other device to help adjust the connection settings.
In the filing’s own words
A method for operating an integrated circuit, including: completing a first link equalization operation with an external integrated circuit; receiving a first signal transmitted by an external transmitter included in the external integrated circuit during an operation at an internal receiver included in the integrated circuit; measuring an eye margin of the first signal at the internal receiver; comparing the measured eye phase with a threshold eye margin to obtain and store a comparison result; transmitting the comparison result as a second signal to an external receiver included in the external integrated circuit using an internal transmitter included in the internal integrated circuit; and performing a second link equalization operation between the external transmitter and the external receiver based on the second signal.
What exactly they claim (claim 1)
1. A method of operating an integrated circuit with an external device, the method comprising: receiving a first signal from the external device during an operation of the integrated circuit; measuring an eye margin of the first signal; storing log data for each operating time based on a measuring result; transmitting a second signal to the external device during the operation; receiving a Get Log Page command in response to the second signal; transmitting the log data corresponding to the Get Log Page command; and performing a link equalization operation based on the log data.
