Abstract

A system includes a memory controller and a plurality of memory devices connected in-series that communicate with the memory controller. Each of the memory devices has multiple independent serial ports for receiving and transmitting data. The memory controller a device address (DA) or ID number for designating a device that executes a command. Data contained in the command sent by the memory controller is captured by an individual link control circuit, in response to internally generated clock with appropriate latencies. The captured data is written into a corresponding memory bank. The data stored in one of a plurality of memory banks of one memory device is read in accordance with the addresses issued by the memory controller. The read data is propagated from the memory device through the series-connected memory devices to the memory controller.
