Segment Reporting [Abstract]  
Segment and Other Information
Segment and Other Information

Segment information reported herein is consistent with how it is reviewed and evaluated by our chief operating decision maker. We have the following four business units, which are our reportable segments:

Compute and Networking Business Unit ("CNBU"): Includes memory products sold into cloud server, enterprise, client, graphics, and networking markets.
Mobile Business Unit ("MBU"): Includes memory products sold into smartphone and other mobile-device markets.
Storage Business Unit ("SBU"): Includes SSDs and other storage products, including component-level solutions sold into enterprise and cloud, client, and consumer SSD markets, other discrete storage products sold in component and wafer forms to the removable storage markets, and sales of 3D XPoint memory.
Embedded Business Unit ("EBU"): Includes memory and storage products sold into automotive, industrial, medical, and consumer markets.

Certain operating expenses directly associated with the activities of a specific segment are charged to that segment. Other indirect operating income and expenses are generally allocated to segments based on their respective percentage of cost of goods sold or forecasted wafer production. We do not identify or report internally our assets (other than goodwill) or capital expenditures by segment, nor do we allocate gains and losses from equity method investments, interest, other non-operating income or expense items, or taxes to segments.
