Providing memory training of dynamic random access memory (DRAM) systems using port-to-port loopbacks, and related methods, systems, and apparatuses are disclosed. In one aspect, a first port within a DRAM system is coupled to a second port via a loopback connection. A training signal is sent to the first port from a System-on-Chip (SoC), and passed to the second port through the loopback connection. The training signal is then returned to the SoC, where it may be examined by a closed-loop training engine of the SoC. A training result corresponding to a hardware parameter may be recorded, and the process may be repeated until an optimal result for the hardware parameter is achieved at the closed-loop training engine. By using a port-to-port loopback configuration, the DRAM system parameters regarding timing, power, and other parameters associated with the DRAM system may be trained more quickly and with lower boot memory usage. |
