A storage controller includes a plurality of pipeline stages configured to process data. A system clock signal is received that has a system frequency and at least one performance metric is determined for one or more pipeline stages of the plurality of pipeline stages. A first clock signal is generated having a first frequency for operation of a first pipeline stage of the plurality of pipeline stages. Based at least in part on the at least one determined performance metric, a second clock signal is generated having a second frequency for operation of a second pipeline stage of the plurality of pipeline stages. The second frequency is less than the system frequency and may also differ from the first frequency.

Power management for storage controllers

Various apparatuses, systems, methods, and media are disclosed to provide over-voltage protection to a data interface of a multi-protocol memory card that includes a first communication interface and a second communication interface that enable communication using different protocols. An interface voltage protection circuit includes a control circuit configured to receive a first supply voltage for operating the first communication interface. The interface voltage protection circuit further includes a pull-down circuit operatively connected with the control circuit, configured to pull down a voltage at a supply voltage rail of the second communication interface such that a voltage at a plurality of connector terminals of the second communication interface is lower than the first supply voltage.

High voltage protection for high-speed data interface

An apparatus includes a circuit and a voltage regulator having a first output terminal that is coupled to provide electrical power to the circuit. The voltage regulator is configured to provide the electrical power in a supply voltage range. The voltage regulator has a second output terminal configured to provide an indicator of electrical current provided by the first output terminal for control of the circuit.
