Abstract
Systems, devices, methods, and circuits for managing power supply in semiconductor devices are provided. The semiconductor devices can include 3D NAND flash memory devices with high capacity and/or high performance. In one aspect, a semiconductor device includes: a voltage pump, a pump switch circuit configured to be coupled to the voltage pump, and an interface including a voltage pin coupled to the pump switch circuit. The voltage pump has an input, an output, and a series of pump stages coupled between the input and the output. The pump switch circuit is configured to provide an input voltage received at the voltage pin to a corresponding node in the voltage pump to select a corresponding number of pump stages of the series of pump stages to output a target voltage at the output of the voltage pump.
