Memory management system with power source and method of manufacture thereof

A method of manufacture of the memory management system includes: fabricating a dual in-line memory module carrier; mounting a volatile memory device on the dual in-line memory module carrier; mounting a non-volatile memory on the dual in-line memory module carrier on a side opposite the volatile memory device; mounting an uninterruptible power supply on the dual in-line memory module carrier for maintaining a memory module power when a system power input decays; and mounting a controller logic integrated circuit on the dual in-line memory module carrier coupled to the volatile memory device, the non-volatile memory, and the uninterruptible power supply for copying data content of the volatile memory device to the non-volatile memory when the uninterruptible power supply detects the decay of the system power input to a first cross-over level.
