Abstract
A solid state drive (SSD) with power loss protection (PLP) and a method of PLP for an SSD is disclosed. In one embodiment, the SSD includes an SSD controller with one or more memory device controllers, a volatile memory in communication with the SSD controller, a non-volatile memory in communication with the SSD controller, and a power circuit in communication with the SSD controller and configured to supply power to the non-volatile memory during a normal operation of the SSD. The non-volatile memory includes a plurality of non-volatile memory devices arranged in a plurality of partitions that are controlled by the one or more memory device controllers. In the event of a power loss or failure, the power circuit supplies power to active partitions, which correspond to less than all of the plurality of partitions of the plurality of non-volatile memory devices.
