DRAM SPECIFIC INTERFACE CALIBRATION VIA PROGRAMMABLE TRAINING SEQUENCES

Methods and systems are disclosed for training, by a sequencer of a memory interface system, an interface with DRAM. Techniques disclosed comprise scheduling a command sequence, including DRAM commands that are interleaved with one or more CSR commands; executing the scheduled command sequence, wherein the DRAM commands are sent to the DRAM through an internal datapath of the system and the CSR commands are sent to the internal datapath; and training the interface based on exchange of data, carried out by the DRAM commands, including adjustments to an operational parameter associated with the interface.
