Original Abstract Submitted
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.
