  • Publication number: 20210022249
    Abstract: A memory system includes a printed circuit board, at least one memory chip mounted on the printed circuit board, and a memory controller arranged on the printed circuit board and connected to 2N (where N is an integer of 2 or more) channels, the memory controller configured to perform a write operation and a read operation on the at least one memory chip. In the printed circuit board, a first subset of the channels corresponds to a first channel group configured in a point to point topology, and a remaining subset of the channels corresponds to a second channel group configured in a daisy chain topology.
    Type: Application

  • Patent number: 10437766
    Abstract: A data storage device is provided. The data store device includes a first printed circuit board (PCB) comprising a main transmission line formed on at least one surface of the first PCB and/or within the first PCB, a memory controller and a plurality of nonvolatile memory devices. The memory controller is provided on the first PCB. The plurality of nonvolatile memory devices are provided on the first PCB. The plurality of nonvolatile memory devices are connected to the memory controller through a channel and exchange data with the memory controller. The channel includes a data transmission line connecting data pads of the memory controller and the nonvolatile memory devices. The data transmission line comprises the main transmission pattern and an open stub contacting the main transmission pattern. The open stub does not contact any other conductor other than the main transmission pattern.
