at the start time the circuit has no energy storage
Memory Circuits
Memory circuits function by storing the voltage present on an input signal whenever they are triggered by a control signal. They retain that stored voltage until the next assertion of the control (or trigger) signal. Between assertions of the control signal, the input signal is ignored and the output is driven to the most recently stored voltage.
