Abstract
Circuits, systems, and methods for discharging loads are provided. One circuit includes a node coupled to a voltage source, a capacitor, a source-follower device coupled between the node and the capacitor, and a current source coupled to the capacitor. The source-follower device is configured to switchably couple the capacitor to the node to discharge the voltage source and the current source is configured to discharge the capacitor. One system includes the above circuit coupled to a memory device such that the circuit is configured to discharge voltage from the memory device. A method includes discharging, via a capacitor coupled to the memory device, a high voltage from the memory device and discharging, via a current source coupled to the capacitor, the high voltage from the capacitor. The capacitor is configured to discharge the high voltage within a predetermined range of time.
