摘要： The present disclosure describes apparatuses and techniques for fail-safe key zeroization. In some aspects a periodic counter is activated that is configured to indicate an amount of time that content of a one-time-programmable (OTP) memory is accessible and overwriting of the content of the OTP is caused when the periodic counter reaches a predetermined value effective to zeroize the content. In other aspects a periodic counter is started in response to a power event and one or more encryption keys stored in OTP memory are zeroized if an indication of media drive security is not received within a predetermined amount of time.
摘要翻译：本公开描述了用于故障安全密钥归零的装置和技术。在一些方面，周期性计数器被激活，其被配置为指示一次性可编程（OTP）存储器的内容可访问的时间量，并且当周期性计数器达到预定值时，引起OTP的内容的重写有效地使内容归零。在其他方面，如果在预定时间内未接收到媒体驱动器安全性的指示，则周期性计数器响应于电力事件而被启动，并且存储在OTP存储器中的一个或多个加密密钥被归零。

摘要： An integrated data storage control system provides, in a single integrated circuit, RDC, servo logic, ATA interface, microprocessor, and other formerly discrete components in one highly integrated system design. The integrated circuit is rendered using a single integrated circuit technology type (e.g., digital CMOS) for all components. Analog and digital circuits are combined in such a way as to eliminate or reduce noise or interference in digital circuits from analog circuit components. Individual elements may have their outputs and inputs MUXed together such that individual elements can be selectively switched (during testing modes) such that the integrated circuit emulates or behaves in the same or similar manner as one of the prior art components. The present invention may be applied to magnetic hard disk drives (HDDs) or other types of storage devices such as floppy disk controllers, optical disk drives (e.g., CD-ROMs and the like), tape drives, and other data storage devices.

摘要： A method of transferring data in one access cycle between two devices over a communications bus. Data is read from a predetermined location in the first device. The data is also latched into a temporary register. Data is simultaneously written into a predetermined location of a second device. The read operation of the first device is terminated and the data from the temporary register is applied to the second device simultaneously with the termination step so that data is available to the second device notwithstanding the fact that the first device has ceased transmission.

摘要： A method and apparatus for reading data from a disk having missing or unreadable field address marks. Expected address marks are searched for within a time window which is generated using a counter. When an expected address mark is generated at any time within the time window, the counter is set or reset to generate another time window within which the next address mark is expected to occur. By starting or restarting the counter each time an expected address mark is detected the effects of variations in spindle speed which occur prior to the detection of the address mark are eliminated, thus increasing the probability that readable address marks will be detected within a time window.
摘要翻译：一种用于从具有丢失或不可读字段地址标记的盘读取数据的方法和装置。在使用计数器生成的时间窗内搜索预期地址标记。当在时间窗口内的任何时候产生预期的地址标记时，计数器被设置或复位以产生预期在其中发生下一个地址标记的另一个时间窗口。每当检测到预期地址标记时，启动或重启计数器，消除了在检测到地址标记之前出现的主轴转速变化的影响，从而增加了在时间窗口内检测可读地址标记的概率。

摘要： A buffer memory subsystem for a peripheral controller. A CPU is provided for initiating data transfer. A host adapter is also provided. A memory buffer is used to store data temporarily. The peripheral controller is adapted for operating in an environment having at least two data communications buses: a CPU data communications bus connected between the CPU and the peripheral controller, and a buffer data communications bus, isolated from the CPU data communications bus, and connected to the peripheral controller, to the memory buffer and to the host adapter. In this way, a mechanism is provided to allow the CPU to access the memory buffer by means of the peripheral controller.
