    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 module and related method are disclosed. The memory module comprises a clock generator configured to generate first and second internal clock signals in relation to an external clock signal, and a register configured to receive the first and second internal clock signals. The register stores an external control/address signal in response to the first internal clock signal and transmits an internal control/address signal derived from the external control/address in response to the second internal control/address signal.

    摘要: A semiconductor memory device capable of determining an operation mode by using states of data pins, and an operation mode determining method for the same are disclosed. The semiconductor memory device includes at least one MRS input pad, at least one data input pad, and an operation mode determining circuit. The operation mode determining circuit generates an operation mode determining signal, when an MRS command input through the MRS input pad corresponds to a predetermined MRS command and data signals input through the data input pad or pads include a predetermined combination. Accordingly, the efficiency in the manufacturing and producing processes may be improved by determining the operation mode of the semiconductor memory device in a module assembly process.
