Abstract
Aspects of dislocated charge storage for power loss protection in non-volatile memory systems are described. A system includes a power supply having an output power stage with bulk capacitance to supply power for a period of time after a power supply failure. The system also includes a network storage interface device and a non-volatile memory media card both coupled to the power supply for power. The power supply is configured to generate a power loss alert in response to the power supply failure. In turn, the network storage interface device is configured to perform a power loss data protection procedure with the non-volatile memory media card based on the power loss alert and during the period of time that the bulk capacitance can supply power after the power supply failure. The additional capacitance typically needed for power loss protection features is located apart from the non-volatile memory media cards.
