Abstract
A data receiving circuit includes a first inductor, a second inductor, and a T-coil equalization circuit. The first inductor is coupled between a first node coupled with a data input/output pad and a second node. The second inductor is coupled between the second node and an internal circuit. The T-coil equalization circuit includes a T-coil with at least one capacitor coupled with the second node. The T-coil equalization circuit is configured to adjust inductive peaking of the T-coil in response to a control signal.

A data training circuit comprising:
- a data receiving circuit coupled with a data input/output pad, the data receiving circuit configured to control inductive peaking according to a control signal and configured to receive data transmitted via the data input/output pad;
- a deserializer configured to deserialize data output from the data receiving circuit to generate parallel data;
- a data verification circuit configured to verify the parallel data to generate a data verification signal;
- and
- a control circuit configured to vary a value of the control signal until the data verification signal has a value indicating that the parallel data has been transmitted normally.
