Embodiments relate to a single multi-output high-voltage (HV) switch configured to pass multiple HV signals in semiconductor integrated circuits, such as a memory device. By utilizing a single HV switch that shares multiple components, area is reduced and fewer numbers of transistor devices are used to reduce cost. The shared components are selected such that the HV switch configuration provides functionality similar to traditional multiple HV switch configurations. Specifically, common logic shared across different branches of the single HV switch enables the single HV switch to provide multiple HV signals.

Embodiments relate to a single multi-output high-voltage (HV) switch configured to pass multiple HV signals in semiconductor integrated circuits. By sharing a single HV switch with multiple components of the semiconductor integrated circuits, the area occupied by the HV switch can be reduced and fewer numbers of transistor devices can be used. Common logic circuit may be used across different branches of the HV switch so that the single HV switch passes HV signals to multiple components.
