The embodiment of the invention provides a dynamic memory parameter calibration method and device, equipment, a medium and a program product, and the method comprises the steps: training a dynamic memory DRAM based on a plurality of groups of test parameters, and obtaining a digital eye diagram corresponding to each group of test parameters; based on a first parameter of the digital eye diagrams, a target digital eye diagram is determined from the digital eye diagrams, and the first parameter is a difference value obtained by subtracting an eye width of the digital eye diagram from a difference value of a maximum reference voltage and a minimum reference voltage in the digital eye diagrams; and determining at least one of a target reference voltage and a write delay of the dynamic memory based on the target digital eye diagram. The optimal target digital eye diagram is searched from the multiple frames of digital eye diagrams through the first parameter, so that the allowance and the eye height allowance are
