  • Publication number: 20230361104
    Abstract: A layout design methodology is provided for a device that includes two or more identical structures. Each device can have a first die, a second die stacked over the first die and a third die stacked over the second die. The second die can include a first through-silicon via (TSV) and a first circuit, and the third die can include a second TSV and a second circuit. The first TSV and the second TSV can be linearly coextensive. The first and second circuit can each be a logic circuit having a comparator and counter used to generate die identifiers. The counters of respective device die can be connected in series between the dice. Each die can be manufactured using the same masks but retain unique logical identifiers. A given die in a stack of dice can thereby be addressed by a single path in a same die layout.

  • Patent number: 11545298
    Abstract: An entangled inductor structure generates opposite polarity internal magnetic fields therein to substantially reduce, or cancel, external magnetic fields propagating outside of the entangled inductor structure. These reduced external magnetic fields propagating outside of the entangled inductor structure effectively reduce a keep out zone (KOZ) between the entangled inductor structure and other electrical, mechanical, and/or electro-mechanical components. This allows the entangled inductor structure to be situated closer to these other electrical, mechanical, and/or electro-mechanical components within the IC as compared to conventional inductors which generate larger external magnetic fields.
