Patent number: 12107076Abstract: Integrated circuits and integrated circuit dies include TSVs laid out in symmetrical patterns. Because of the symmetrical arrangement of the TSVs and associated routing patterns, an integrated circuit is able to support operation of multiple similar dies that are placed in different positions in the integrated circuit. This in turn simplifies the design and production of the multiple similar dies, thus reducing development and manufacturing costs for the corresponding integrated circuits.Type: GrantFiled: December 28, 2021Date of Patent: October 1, 2024Assignees: Advanced Micro Devices, Inc., ATI Technologies ULCInventors: Wonjun Jung, Jasmeet Singh Narang, Tyrone Huang, Christopher Klement, Alan D. Smith, Edward Chang, John Wuu
