Abstract
Approaches, techniques, and mechanisms are disclosed for a centralized backup power support system that improves testability of non-volatile dual in-line memory modules (NVDIMM) on Automatic Test Equipment (ATE) testers and in-system tests. An NVDIMM includes both volatile memories and non-volatile memories. According to an embodiment, a compact backup power distribution board is powered with an external power supply with an individual protection circuit. The backup power distribution board has an unlimited energy capacity for any density of NVDIMM and zero charge waiting time. According to an embodiment, instead of using an electric double-layer capacitor (EDLC) to support backup power, a resistor is used instead of an EDLC on each backup power module. There is no charging time when the backup power module does not have EDLC cells, resulting in significant reduction in test time and production cost and increase in production output.
