Data streaming for solid-state bulk storage devices

摘要

Methods facilitate data streaming in bulk storage devices by generating linked lists containing entries for both user data and metadata. These linked lists containing mixed data types facilitate receiving and outputting user data, and to insert or ignore, respectively, metadata corresponding to that user data without interrupting flow of the user data.

1. A method of operating a storage device, comprising:
generating a linked list in response to decoding an access command received at the storage device, wherein the linked list has two or more first entries corresponding to user data, two or more second entries corresponding to metadata, and a defined order of the first entries and the second entries corresponding to a defined data structure of a page of data of a first memory of the storage device, wherein each first entry of the linked list identifies a size of a respective portion of user data and a starting address for storage of that portion of user data to a second memory of the storage device, and wherein each second entry of the linked list identifies a size of a respective portion of metadata and a starting address for storage of that portion of metadata to the second memory of the storage device; storing portions of user data and portions of metadata to the second memory according to the sizes and the starting addresses identified by the ordered entries of the linked list; and outputting at least the stored portions of user data from the second memory.
