    摘要: A DLL of a memory device having a normal mode and a power down mode includes a clock buffer for buffering an external clock signal to output an internal clock signal. A power down mode controller generates a power down mode control signal to define the normal mode or the power down mode in response to a clock enable signal. A source clock generation unit receives the internal clock signal to generate a DLL source clock signal under the control of the power down mode control signal. A phase update unit performs a phase update operation based on the DLL source clock signal to output a DLL clock signal.

    摘要: There is provided a multi-port memory device, which is capable of preventing a first high data fail phenomenon at an initial operation in a current sensing type global data bus transmission/reception structure without causing a problem in a low data transmission. In the multi-port memory device having a data transmission/reception block (bank, port, global data bus connection block, etc.) which exchanges data with the global data bus in a current sensing type data transmission/reception structure, an initialization switch is used to discharge each global data bus line and an initialization signal generator controls the initialization switch. A first high data fail at the initial operation is caused by a high precharge level of the global data bus. According to the present invention, it is possible to lower a high precharge level without causing a problem in data transmission.
