Abstract
Various implementations described herein relate to systems and methods for managing metadata using an in-memory journal, including determining metadata for data, storing the metadata in an in-memory journal, detecting an imminent interruption to operations of the storage device, in response to detecting the imminent interruption, program the in-memory journal to a non-volatile memory device of the storage device, detect that the operations of the storage device are being restored, and in response to detecting that the operations of the storage device are being restored, performing metadata update. The first data is read from first original areas of a non-volatile memory. The first metadata includes a first physical address for each of first new areas of the non-volatile memory. The metadata is programmed in a metadata area of the non-volatile memory device.
