A processing circuit (12) coupled to the read access circuit (14, 16, 18) is configured to execute an extra read operation involving issuing the read command, receiving the extra data (24), performing error detection on only the extra data (24), using an error detecting code in which the extra data is coded, conditionally performing error correction on the data from the extra data (24) using data from the retrieval unit including the payload data (22), according to an error correcting code in which the retrieval unit is coded, if the error detection indicates an error in the extra data (24). The processing circuit (12) performs further processing using the data from the extra data (22) or the corrected extra data, dependent on whether the error detection indicates an error in the extra data (22).

    Abstract: The present invention provides a special structure of magnetic elements, e.g. MRAM elements, as a security device for IC's containing magnetic memory cells. In an example embodiment, the structure may comprise a combination of two or more associated magnetic elements with pre-set anti-parallel magnetization directions. By determining the polarisation directions of the magnetic elements, exposure to an external magnetic field can be detected. Inverse polarisation directions indicate a normal situation, aligned polarisation directions indicate that the MRAM-array has been exposed to an external field. In this way it can be detected whether a user has tried to erase or alter the data stored in the MRAM in an illegal way. The IC can regularly check the resistance of the security system during operation. Upon detection of a field exposure, the IC can erase all MRAM data, reset itself or, block its functioning.

    Abstract: A computer system includes a system memory (SM) and a non-volatile memory (NVM). The computer system is arranged to copy at least a part of the system state, stored in the system memory during a clean boot-up procedure, into the non-volatile memory (209, 329). During subsequent start-ups of the computer system, the system state is copied from the non-volatile memory into the system memory (205, 305), resulting in a significantly faster system start-up. In case the configuration of the computer system has changed, the complete boot-up procedure is executed again and the new system state is copied into the non-volatile memory, overwriting the previously stored system state.

    Abstract: Real-time audio video applications require guaranteed request service times from a hard disc drive. This requirement is not always fulfilled due to some unexpected delays in service times. Re-allocated sectors are one of the causes of such delays. A scheme for conversion of re-maps into slips in a hard disc drive is suggested. Converting re-allocated sectors into slipped or skipped sectors can prevent such a delay, since slipped sectors cause much less or even negligible performance loss than re-allocated sectors.

    Abstract translation: 实时音频视频应用程序需要硬盘驱动器的保证请求服务时间。 由于服务时间出现一些意想不到的延迟,这一要求并不总是得到满足。 重新分配的部门是造成这种拖延的原因之一。 建议将重新映射转换为硬盘驱动器中的单据的方案。 将重新分配的扇区转换成滑动或跳过的扇区可以防止这种延迟,因为滑动的扇区比重新分配的扇区导致更少甚至可忽略的性能损失。

    Abstract: The present invention provides a special structure of magnetic elements, e.g. MRAM elements (10, 11), as a security device (30) for IC's containing magnetic memory cells. The structure may comprise a combination of two or more associated magnetic elements (10, 11) with pre-set anti-parallel magnetization directions. By determining the polarisation directions of the magnetic elements, exposure to an external magnetic field can be detected. Inverse polarisation directions indicate a normal situation, aligned polarisation directions indicate that the MRAM-array has been exposed to an external field.

    Abstract: Consumer electronic devices that run on a battery or an accumulator—i.e. particularly portable applications such as mobile phones, laptops or MPEG players or recorders-require the management of power consumption. They consist essentially of a host and a storage medium like a disk or means for receiving a storage medium like a disk drive that are coupled with an interface. Power management is very important because long battery life enhances user convenience. According to the invention, it is determined whether it is more efficient either to leave the disk drive in the idle mode or to switch the drive to standby until the next data request appears. The disk drive is entered into the most efficient power mode. The time until the next request is determined by the host.

    Abstract: A method and apparatus for translating a voltage control signal to switch a drive output, having a circuit with a pair of branches, each branch having a pull down device, respective branches receiving complementary components of the voltage control signal; a pull up device, in series with a respective pull down device, and each being driven by a positive feedback signal reflecting a state of conduction of the pull up device; and a current blocking device, in series with the pull up device, having a control input for impeding a current flowing in series to a respective pull down device. One current blocking device is controlled to selectively block a current flow through one of the branches, while permitting current flow through the other branch. The state of the voltage control signal is switched, current flow through both branches is resumed. In a preferred embodiment, the complementary components of the voltage control signal are formed with an inverter. A transmission gate is provided, having a pair of complementary inputs from the nodes between the pull up devices and pull down device in series, to modulate the optical state of a liquid crystal light modulating structure. The pull down devices, pull up devices, current blocking devices, inverter and complementary device transmission gate are each preferably formed in a silicon integrated circuit, with the liquid crystal light modulating structure formed on the surface.
