A method of operation of a non-volatile dynamic random access memory system including: accessing a dynamic random access memory; managing a delay-locked-loop control in the dynamic random access memory; sourcing timing inputs to the dynamic random access memory by a control logic unit with the delay-locked-loop control disabled including: selecting a back-up interface through a first multiplexer and a second multiplexer, asserting an on-board termination, and accessing data in the dynamic random access memory by the control logic unit at a lower frequency; and enabling a memory control interface by the control logic unit, with the delay-locked-loop control enabled including: selecting a host interface through the first multiplexer, the second multiplexer, or a combination thereof, disabling the on-board termination, and accessing the data in the dynamic random access memory by the memory control interface at a delay-locked-loop frequency.
