Abstract: The feature size of semiconductor devices continues to decrease in each new generation. Smaller channel lengths lead to increased leakage currents. To reduce leakage current, some power domains within a device may be powered off (e.g., power collapsed) during periods of inactivity. However, when power is returned to the collapsed domains, circuitry in other power domains may experience significant processing overhead associated with reconfiguring communication channels to the newly powered domains. Provided in the present disclosure are exemplary techniques for isolating power domains to promote flexible power collapse while better managing the processing overhead associated with reestablishing data connections.

Abstract translation: 半导体器件的特征尺寸在每一代新一代继续下降。 较小的通道长度导致泄漏电流增加。 为了减少泄漏电流，在不活动期间，器件内部的一些电源域可能被断电（例如，电源崩溃）。 然而，当电力返回到折叠域时，其他电力域中的电路可能经历与重新配置到新供电域的通信信道相关联的显着处理开销。 在本公开中提供的是用于隔离功率域以促进柔性功率崩溃的示例性技术，同时更好地管理与重新建立数据连接相关联的处理开销。
