摘要： Random numbers are generated using entropic properties associated with circuit hardware. Consistent with one method, a switching voltage regulator circuit is used to generate a random number. Data that is responsive to switching states of the switching voltage regulator circuit is generated. A multi-bit random number is then generated from the generated data.

摘要： A data storage device has encrypted user data and a media key stored on media, and a root key stored in an electronic circuit. The data storage device has a first connector adapted to receive a user key and a hardware key device connected to a second connector adjacent an installation space. The hardware key device stores a destructible key in non-volatile memory. The hardware key device is mechanically destroyed, thereby rendering the encrypted user data non-decipherable after the destroying.

摘要： Power-backup capabilities are provided by implementing a variety of different methods, systems and devices. According to one such implementation, a data-storage device is implemented having a memory control circuit controlling non-volatile and volatile memory. An operating power circuit carries primary-operating power from the host-system to the memories and control circuitry. A backup power circuit includes energy-storage circuitry with one or more energy storage devices. An isolation-regulation circuit provides voltage regulation of power from the host-system and also isolates the host-system provided power from the energy storage devices. A regulation power circuit carries the regulated power from the isolation-regulation circuit to the energy storage devices.

摘要： In general, this disclosure describes techniques for implementing a system-wide reset of multiple devices. The techniques ensure that when any one of the devices of the system is reset, all the devices are reset. For example, a system includes a master reset device and a plurality of slave reset devices that are interconnected by a single reset line to provide improved robustness against electrostatic discharge (ESD) and electromagnetic pulse events. The master reset device detects a reset signal on the reset line and retransmits a true reset signal on the reset line in response to detecting the reset signal. Additionally, the master reset device may enter a blocking state after retransmitting the true reset signal to prevent detecting the reset signal that it transmitted on the reset line to avoid reset lockup.
摘要翻译： 通常，本公开描述了用于实现多个设备的系统范围复位的技术。 这些技术确保当系统的任何一个设备被复位时，所有的设备都被复位。 例如，系统包括主复位装置和多个从复位装置，其通过单个复位线互连以提供抵抗静电放电（ESD）和电磁脉冲事件的改善的鲁棒性。 主复位装置检测复位线路上的复位信号，并响应于检测到复位信号而在复位线路上重发真实复位信号。 此外，主复位装置可以在重传真实复位信号之后进入阻塞状态，以防止检测其在复位线上发送的复位信号，以避免复位锁定。

摘要： Power is routed from one or more power supplies. As consistent with one or more example embodiments, a data storage device senses and/or is informed of the availability and voltage level of one or more power supplies. Based upon the availability and voltage level of power supplies, circuits in the memory device are powered using one or more of the sensed power supplies. In some applications, the power is drawn in a manner that emulates the behavior of one or more circuits that are respectively powered.
