Samsung patents chip method to fine-tune data links between circuits
This patent describes a method where one integrated circuit measures the quality of a data signal received from another chip. It compares this quality against a set limit and sends the result back to help adjust the connection for clearer data transfer.
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 for operating an integrated circuit, the method comprising: 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 margin 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 integrated circuit; and performing a second link equalization operation between the external transmitter and the internal receiver based on the second signal, wherein the second signal corresponds to an asynchronous event request (AER).
