    • 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
