    • In one embodiment of the present invention, a memory controller is provided that includes both a first processor and a second processor. If a memory device controlled by the controller indicates to the controller that an error condition exists in the device, either the first processor or the second processor is selected to handle the error condition. If the first processor is selected to handle the error condition, the first processor handles the error condition according to one or more statically preprogrammed error handling routines. Conversely, if the second processor is selected to handle the error condition, the second processor handles the error condition according to one or more dynamically programmable error handling routines.
    • 在本发明的一个实施例中,提供一种包括第一处理器和第二处理器的存储器控​​制器。 如果由控制器控制的存储器件向控制器指示设备中存在错误状况,则选择第一处理器或第二处理器来处理错误状况。 如果选择第一处理器来处理错误条件,则第一处理器根据一个或多个静态预编程的错误处理例程处理错误状况。 相反,如果选择第二处理器来处理错误状况,则第二处理器根据一个或多个动态可编程错误处理例程处理错误状况。

    • A data transmission system includes a first data transmission device for receiving commands from a host; a second data transmission device for transmitting commands to a memory device; and a crossbar device for receiving commands from the first data transmission device over a first link and transmitting the commands to the second data transmission device over a second link. The crossbar device includes status logic to detect a command transmission error on the first link from the first data transmission device and transmits a retry command to prompt the first data transmission device to retry the transmission of the command over the first link. The second data transmission device reports a transmission error on the second link to the status logic of the crossbar device and the status logic of the crossbar device transmits the retry command to prompt the first data transmission device to retry the transmission of the command over the first link.
    • 数据传输系统包括用于从主机接收命令的第一数据传输装置; 第二数据发送装置,用于向存储装置发送命令; 以及横杆装置,用于通过第一链路从第一数据传输装置接收命令,并通过第二链路将命令发送到第二数据传输装置。 交叉开关装置包括用于检测来自第一数据传输装置的第一链路上的命令传输错误的状态逻辑,并发送重试命令以提示第一数据传输装置通过第一链路重新发送命令。 第二数据传输装置在第二链路上报告交叉开关装置的状态逻辑的传输错误,并且横杠装置的状态逻辑发送重试命令以提示第一数据传输装置在第一数据传输装置上重新发送命令 链接。
