    • PROBLEM TO BE SOLVED: To provide an apparatus and a method that allocate I/O bandwidth of an electrical component, such as an IC, by configuring an I/O interface into various types of interfaces.SOLUTION: An I/O interface is configured into either a bidirectional contact, unidirectional contact or a maintenance contact used in a maintenance or calibration mode of operation. The I/O interface is periodically reconfigured to optimally allocate I/O bandwidth responsive to system parameters, such as changing data workloads in the electronic components. System parameters include: the number of transmit-receive bus turnarounds; the number of transmit and/or receive data packets; user selectable setting; the number of transmit and/or receive commands; direct requests from one or more electronic components; the number of queued transactions in one or more electronic components; transmit burst-length setting; and duration or cycle count of bus commands.
    • 要解决的问题:提供通过将I / O接口配置成各种类型的接口来分配诸如IC的电气部件的I / O带宽的装置和方法。解决方案:配置I / O接口 进入维护或校准操作模式中使用的双向触点,单向触点或维护触点。 周期性地重新配置I / O接口,以响应于系统参数(例如改变电子组件中的数据工作负载)来最佳地分配I / O带宽。 系统参数包括:发送接收总线周转数; 发送和/或接收数据包的数量; 用户可选设置; 发送和/或接收命令的数量; 来自一个或多个电子部件的直接请求; 在一个或多个电子组件中排队交易的数量; 发送突发长度设置; 以及总线命令的持续时间或周期数。

    • PROBLEM TO BE SOLVED: To modify a data strobe which allows corresponding to a system that runs faster. SOLUTION: Memory devices 130/440/450-1 to 130/440/450-8 have two operating modes. In a first mode the data strobes, 170-1 to 170-8 are source synchronous and are driven by the memory devices when data is being transmitted. In a second mode, the data strobes are not driven by the memory devices. In this mode, the data strobe signals 170-1 to 170-8 are used as a free running clock for sampling write data. Capture of the data read by a controller 110/425 is timed by the controller 110/425, by using a calibrated internal timing reference from a system clock. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:修改允许对应于运行更快的系统的数据选通。

      解决方案:存储器件130/440 / 450-1至130/440 / 450-8具有两种工作模式。 在第一模式中,数据选通信号170-1至170-8是源同步的,并且当数据被发送时由存储器件驱动。 在第二模式中,数据选通不由存储器件驱动。 在该模式中,数据选通信号170-1至170-8用作用于对写入数据进行采样的自由运行时钟。 由控制器110/425读取的数据的捕获由控制器110/425通过使用来自系统时钟的经校准的内部定时参考来定时。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To share a check bit memory device between groups of memory devices.SOLUTION: A memory system that supports error detection and correction (EDC) coverage. The memory system includes: a memory module with at least two groups of memory devices that store data and another memory device that stores error checking information (e.g., Error Correcting Code) for both groups of memory devices. The memory module also includes a memory buffer that determines an address for accessing the error checking information on the basis of whether data is transferred with the first group of memory devices or the second group of memory devices. Alternatively, the memory controller may determine the address for accessing the error checking information to reduce or eliminate the need for the memory buffer.
    • 要解决的问题:在存储器件组之间共享校验位存储器件。 解决方案:支持错误检测和纠正(EDC)覆盖的内存系统。 存储器系统包括:具有存储数据的至少两组存储器件的存储器模块和存储两组存储器件的错误检查信息(例如,错误校正代码)的另一存储器件。 存储器模块还包括存储器缓冲器,其基于是否利用第一组存储器件或第二组存储器件传送数据来确定用于访问错误检查信息的地址。 或者,存储器控制器可以确定用于访问错误检查信息的地址以减少或消除对存储器缓冲器的需要。 版权所有(C)2013,JPO&INPIT
