According to an example, a dual-port non-volatile dual in-line memory module (NVDIMM) includes a first port to provide a central processing unit (CPU) with access to universal memory of the dual-port NVDIMM and a second port to provide an external NVDIMM manager circuit with access to the universal memory of the dual-port NVDIMM. Accordingly, a media controller of the dual-port NVDIMM may store data received from the CPU through the first port in the universal memory, control dual-port settings received from the CPU, and transmit the stored data to the NVDIMM manager circuit through the second port of the dual-port NVDIMM.
