  • Publication number: 20230410891
    Abstract: A method for using a high bandwidth memory controller includes providing a clock signal having a first clock frequency, providing a write strobe signal having a second clock frequency, providing a write command/address signal based on the clock signal, and providing a write data signal based on the write strobe signal. The first clock frequency is half of the second clock frequency, the write strobe signal has two cycles of pre-amble before the write data signal, and the write strobe signal has two cycles of post-amble after the write data signal.

  • Patent number: 11309014
    Abstract: Disclosed is a memory device, which includes a buffer die that outputs a first power supply voltage to a first through-substrate via (e.g., through-silicon via (TSV)) and receives a small swing data signal from a second TSV generated based on the first power supply voltage, and a core die that is electrically connected to the buffer die through the first and second TSVs, includes a first cell capacitor electrically connected to the first TSV and configured to block a first noise introduced to the first power supply voltage received through the first TSV. The core die outputs the small swing data signal to the second TSV.

  • Patent number: 11295808
    Abstract: A memory device includes a control logic circuit, a write data strobe signal divider, a data transceiver, and a memory cell array. The control logic circuit generates a reset signal before a write data strobe signal provided from a memory controller starts to toggle. The write data strobe signal divider generates internal write data strobe signals that toggle depending on toggling of the write data strobe signal, the internal write data strobe signals toggling with different phases, respectively. The control logic circuit initializes the internal write data strobe signals to given values in response to the reset signal. The data transceiver receives write data provided from the memory controller based on the internal write data strobe signals. The memory cell array stores the received write data.
