摘要： A hard disk drive enters a low power mode to reduce power consumption. To maintain communication with a host device, a communication interface remains energized along with a circuit portion storing configuration data for the communication interface. To energize the communication interface and the circuit portion, low power voltage regulators provide suitable reference voltages. One low power voltage regulator is dedicate to this purpose. Another voltage regulator is converted from an active, switching mode to a low power, linear mode to provide the necessary reference voltage. Also, unique handshaking signals are used to control entry and exit from the low power mode by the hard disk drive.

摘要： A hard disk drive enters a low power mode to reduce power consumption. To maintain communication with a host device, a communication interface remains energized along with a circuit portion storing configuration data for the communication interface. The hard disk drive may have a Universal Serial Bus (USB) interface to provide two-way communication to external data processing equipment. The hard disk drive may have a system on a chip (SoC) core to issue the low power mode entry command. During the low power mode, circuitry for external communication is kept in an active state.
摘要翻译：硬盘驱动器进入低功耗模式以降低功耗。为了保持与主机设备的通信，通信接口与存储用于通信接口的配置数据的电路部分保持通电。硬盘驱动器可以具有通用串行总线（USB）接口，以向外部数据处理设备提供双向通信。硬盘驱动器可以具有芯片（SoC）核心的系统以发出低功率模式输入命令。在低功率模式期间，用于外部通信的电路保持在活动状态。

摘要： Apparatus and method are provided for accessing information in a storage area including a storage area which is accessible by a first buss and a second buss. The access by the first buss is clocked by a first clock signal and the access by the second buss is clocked by a second clock signal. The first clock signal has a first clock frequency and the second clock signal has a second clock frequency. A terminal receives a base clock signal having a frequency of at least the sum of the first clock frequency and the second clock frequency. An access to the storage area by the first or second buss is made during a cycle of the base clock.
