Abstract: Methods of operating a power supply switching circuit including selecting a first power supply signal for provisioning through the power supply switching circuit to a electronic storage device. A current draw can be detected via the first power supply signal that exceeds a predetermined current limit and a second power supply signal can be coupled to the first power supply signal for provisioning through the power supply switching circuit to the electronic storage device responsive to the current draw exceeding the predetermined current limit.

Abstract: Disclosed is a fan-out buffer which includes a first channel that includes a first delay circuit adjusting a first delay time of a calibration test signal depending on a first delay control signal, a second channel that includes a second delay circuit adjusting a second delay time of the calibration test signal depending on a second delay control signal, a first edge-to-pulse converter that detects a first edge included in a first time domain reflectometry (TDR) waveform of an output terminal of the first channel and generates a first start pulse signal including a first pulse, a second edge-to-pulse converter that generates a second start pulse signal including a second pulse, a stop pulse signal generator that generates a stop pulse signal including a first stop pulse, and a first delay control signal generator that calculates a phase difference generates the first delay control signal.
