    • A method of operation in a memory controller comprising generating a mode control signal to specify at least one of a first and second mode is disclosed. In the first mode, the memory controller is configured to operate by issuing a memory access command to initiate a first data transfer between the memory controller and a first memory device, and generating a strobe signal to accompany data associated with the first data transfer. In the second mode, the controller is configured to operate by issuing a memory access command to initiate a second data transfer between the memory controller and at least first and second memory devices involving a full width that includes data widths of both the first and second memory devices, and issuing first and second strobe signals that accompany respective data transfers associated with each of the data widths of the first and second memory devices.
    • 公开了一种在存储器控制器中的操作方法,包括生成模式控制信号以指定第一和第二模式中的至少一个。 在第一模式中,存储器控制器被配置为通过发出存储器访问命令来操作,以启动存储器控制器和第一存储器件之间的第一数据传输,并且产生选通信号以伴随与第一数据传输相关联的数据。 在第二模式中,控制器被配置为通过发出存储器访问命令来进行操作,以在存储器控制器与包括全宽度的至少第一和第二存储器件之间的第二数据传输中包括第一和第二存储器的数据宽度 并且发出伴随与第一和第二存储器设备的每个数据宽度相关联的相应数据传输的第一和第二选通信号。
