    • There is provided a method of increasing boot-up speed in a computer system (10). The system (10) includes computing devices (20) for processing data and a data store (60) coupled thereto for providing data to and receiving data from the devices (20). The store (60) is operable to write and/or read data in several regions (T1, T2, T3) of a data medium (200). Access between the regions is subject to associated jump delays (SK1/2, SK2/3; SK1/3, SL3/2). The store (60) includes a cache (320) for temporarily storing data read from and/or for writing data to the medium (200). On initial boot-up of the system (20), a log is made of a sequence in which the regions (T1, T2, T3) are accessed. Moreover, on subsequent boot-up of the system (10), the log is used to store data read from the medium (200) temporarily in the cache (310, 320) so as to provide for a more temporally efficient sequence of accessing the regions (T1, T2, T3) for speeding up said subsequent boot-up.
    • 提供了一种在计算机系统(10)中增加启动速度的方法。 系统(10)包括用于处理数据的计算设备(20)和与其耦合的数据存储(60),用于向设备(20)提供数据和从设备(20)接收数据。 存储器(60)可操作以在数据介质(200)的若干区域(T 1,T 2,T 3)中写入和/或读取数据。 区域之间的接触受到相关的跳跃延迟(SK 1/2,SK 2/3; SK 1/3,SL 3/2)。 存储器(60)包括用于临时存储从数据读取和/或写入到介质(200)的数据的高速缓存(320)。 在系统(20)的初始启动时,日志由访问区域(T 1,T 2,T 3)的序列组成。 此外,在系统(10)的后续启动时,日志用于将从媒体(200)中读取的数据临时存储在高速缓存(310,320)中,以便提供更时间有效的访问序列 区域(T 1,T 2,T 3),用于加速所述随后的启动。

    • A universal memory device is presented that provides adaptability to existing hardware and software environments. The memory can “mimic” existing memory technology combining the advantages of integrating all memory capacity into one single technology and still providing the implicit protections and access characteristics known from the different existing memory technologies. The memory device comprises a memory having low-latency, rewritable, non-volatile memory cells, a profile storage unit connected with the memory and comprising access information allocated to a set of request information elements (request profile), such that the access information indicates whether an access request to said memory, the access request having the request profile, is to be allowed or rejected, and an access control unit communicating with the profile storage unit and the memory, and adapted to allow or reject an incoming access request in dependence on the access information allocated to the request profile of the access request.

    • 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.
    • 本发明提供了一种磁性元件的特殊结构。 MRAM元件作为包含磁存储单元的IC的安全装置。 在示例性实施例中,该结构可以包括具有预设的反并联磁化方向的两个或更多个相关联的磁性元件的组合。 通过确定磁性元件的极化方向,可以检测到暴露于外部磁场。 反偏振方向表示正常情况,对准偏振方向表示MRAM阵列暴露于外部场。 以这种方式,可以检测用户是否尝试以非法方式擦除或更改存储在MRAM中的数据。 IC可以在运行期间定期检查安全系统的电阻。 在检测到场曝光时,IC可以擦除所有MRAM数据,自身复位或阻止其功能。

    • Method for writing a label on a recordable record carrier (1), the record carrier adhering to a predefined, standardized condition with respect to a physical parameter. The method retrieves label information, parameter information on the physical parameter, which parameter information is of a higher precision than the precision of the physical parameter mentioned in the pre-defined, standardized condition (22), and writing the label information on the optical disc using the parameter information (26). The invention further relates to a device for performing the method. Retrieving parameter information on the physical parameter with a higher precision than the precision of the physical parameter mentioned in the pre-defined, standardized condition enables writing such a label without a significant distortion in the label.
