Abstract:
A computer system having a host coupled to a storage device via a peripheral component interconnect express bus. The host communicates with the storage device in accordance with a non-volatile memory host controller interface specification. The storage device stores versions of meta data sequentially in a portion of a volatile memory that is protected against power failure using a power hold-up module. In response to a sudden power loss, the power hold-up module provides sufficient energy to support operations to copy the content from the portion of the volatile memory into a non-volatile memory. During a startup process, the content is retrieved from the non-volatile memory; and a binary search is performed to locate, within the content, the latest, valid version of the meta data to continue operations interrupted by the power loss.
