Hybrid memory module and system and method of operating the same

A method performed by a memory module coupled to a memory controller via a system bus in a computer system, the system bus including a data bus and a control/address (C/A) bus, the memory module including a volatile memory subsystem, a non-volatile memory subsystem, the method comprising:

• receiving a first command from the memory controller via the C/A bus;
• in response to the first command being a command to transfer first data from the non-volatile memory subsystem to the volatile memory subsystem, receiving via the data bus first information associated with the first command, the first information including at least one of a first address in the non-volatile memory subsystem at which the first data is located and a second address in the volatile memory subsystem to which the first data is to be transferred, and reading the first data requested by the first command from the non-volatile memory subsystem;
• receiving a dummy write memory command from the memory controller via the C/A bus;
• and
• in response to the dummy write memory command being associated with the first command, providing at least one portion of the first data to the volatile memory subsystem a certain time period after receiving the dummy write memory command so that the at least one portion of the first data appear at data inputs/outputs (I/O) of the volatile memory subsystem in accordance with a latency parameters of the volatile memory subsystem, and receiving the at least one portion of the first data at the volatile memory subsystem in response to the dummy write memory command.
