A memory element is provided in which a logical state can be securely stored in all conditions even when input set and reset signals are overlapping. This is achieved through provision of an array of persistence latches with an asynchronous circuit that ensures correct operation. The persistence latches provide a persistent output for each of the first and second edges of each input. The memory element is arranged to receive a plurality of inputs including a first and second input. Each first and second inputs include a digital signal that can transition between a first state via a first edge which triggers transition from the first state to the second state and a second edge which triggers transition from the second state to the first state.

Secure memory element for logical state storage

A circuit for driving a power switch is presented. The circuit includes a first power switch coupled to a second power switch via a switching node and a driver coupled to the first power switch, where the driver contains an energy storing element coupled to the switching node. The circuit also contains a sensor to sense an electrical parameter of the driver and a charger coupled to the sensor. The charger provides a charge current to charge the energy storage element, and to control the charge current based on the electrical parameter. In particular, a circuit for driving a power switch based on a III/V semiconductor is presented. In addition, a method of powering a power switch driver is presented. The method includes sensing an electrical parameter of the driver and adjusting a current to charge the energy storing element based on the electrical parameter.
