    • According to the invention, systems, apparatus and methods are disclosed for automatically replacing semiconductor based memory in a system while that system is operating. Replacement is accomplished by blocking access to the memory devices to be swapped, copying the contents of the faulty device to the replacement device, swapping the IDs of the two devices, and re-enabling access to the replaced device. This replacement is triggered by interrupts from the error detection logic. After replacement, the system automatically checks the faulty device to determine its suitability for use as a spare in the future. The determination is made by repeatedly writing and reading a pseudo-random pattern into the device and logging any errors.
    • 根据本发明,公开了系统,装置和方法,用于在系统运行时自动替换系统中的半导体存储器。 替换是通过阻止访问要交换的存储设备,将故障设备的内容复制到替换设备,交换两个设备的ID,以及重新启用对更换的设备的访问来实现的。 该更换由错误检测逻辑的中断触发。 更换后,系统会自动检查故障设备,以确定其将来适合作为备用设备使用。 通过重复写入和读取伪随机模式到设备中并记录任何错误来进行确定。
