Method and apparatus for high bandwidth memory read and write data path training

According to certain general aspects, the present embodiments relate to methods and apparatuses for performing read and write data path training in HBMs. In accordance with some aspects, embodiments configure HBM mode registers for read and write data path training using an IEEE 1500 interface is simpler than the traditional scenario. In accordance with other aspects, the logic for performing read and write data path training is independent from normal memory access functionality in the host, capable of independently interacting with a PHY core for performing read and write data path training.
