    摘要: A memory module includes: an ODT circuit on a memory device and including pull-up and pull-down resistors connected between pull-up and pull-down transistors. A data masking (DM) pad is provided in a tap region of the module board. A current leakage monitoring unit is also provided and receives a ground state signal from the DM pad and a bit configuration signal from the memory device and disables the pull-up transistors to cut off a current path between the pull-up resistors of the ODT circuit and the DM pad during a ODT enable mode.

    摘要: A memory buffer selecting between a parallel test mode and a mode register control mode, and a memory module and memory system having the memory buffer are disclosed. The memory buffer includes a control circuit and a mode selecting circuit. The control circuit generates a mode control signal based on a first chip selecting signal, a second chip selecting signal, a row address signal, a column address signal, and a write enable signal. The mode selecting circuit selects one of a parallel test mode and a mode register control mode in response to the mode control signal.
