    • A stacked semiconductor chip comprising multiple unit chips contains multiple instances of a first chip component that have a low yield and are distributed among the multiple unit chips. An instance of the first chip component within a first unit chip is logically paired with at least another instance of the first chip component within at least another unit chip so that the combination of the multiple instances of the first chip component across the multiple unit chips constitute a functional block providing the functionality of a fully functional instance of the first chip component. The stacked semiconductor chip may include multiple instances of a second chip component having a high yield and distributed across the multiple unit chips. Multiple low yield components constitute a functional block providing an enhanced overall yield, while high yield components are utilized to their full potential functionality.
    • 包括多个单元芯片的堆叠半导体芯片包含具有低产出并分布在多个单元芯片之间的第一芯片组件的多个实例。 第一单元芯片内的第一芯片组件的实例与至少另一个单元芯片内的第一芯片组件的至少另一个实例进行逻辑配对,使得跨多个单元芯片的第一芯片组件的多个实例的组合构成 提供第一芯片组件的完全功能实例的功能的功能块。 层叠的半导体芯片可以包括具有高产量并分布在多个单元芯片上的第二芯片组件的多个实例。 多个低产量组分构成提供增强的总收率的功能块,而高产量组分被用于其全部潜在功能。
