Research and Development [Abstract]
Research and Development	Research and Development We share the cost of certain product and process development activities with development partners. Our R&D expenses were reduced by $6 million and $59 million for the third quarter and first nine months of 2019, respectively, and by $53 million and $167 million for the third quarter and first nine months of 2018, respectively, pursuant to reimbursements under these arrangements. In the second quarter of 2018, we and Intel agreed to independently develop subsequent generations of 3D NAND. Our 3D NAND joint development agreement with Intel was substantially completed in the third quarter of 2019. In the fourth quarter of 2018, we announced that we and Intel will no longer jointly develop 3D XPoint technology beyond the second generation. We expect development of the second generation of 3D XPoint technology to be substantially completed in the first quarter of 2020.
