    摘要: A semiconductor memory device includes first and second global data line pairs connected to a local data line pair, allowing a reduced pre-charge voltage that lowers current consumption and increases operating speed. Also included are a sense amplifier for amplifying data of the second global data line pair and outputting the amplified data to a data line, and a write driver for outputting data of the data line to the first global data line pair during a write operation. Switching circuits are connected between the first and second global data line pairs, and the local data line and the first global data line pairs. The memory device further includes a first global data line pre-charge circuit for pre-charging the first global data line pair to a first voltage level, and a second global data line pre-charge circuit for pre-charging the second global data line pair to a second voltage level.

    摘要: A word line driver for use in a semiconductor memory device includes a boosted voltage generator, a sub word line driver and a main word line driver. The boosted voltage generator generates a boosted voltage by receiving an internal power supply voltage and pumping electric charge. The sub word line driver receives the internal power supply voltage and activates a boosted voltage control signal after supplying the internal power supply voltage to a boost node in a command operating mode. The main word line driver enables a word line by supplying the boosted voltage to the boost node in response to the boosted voltage control signal in a normal operating mode, and enables the word line with the boosted voltage after boosting the word line to the internal power supply voltage by changing the boost node from the internal power supply voltage to the boosted voltage in the command operating mode.

    摘要: In an embodiment, a semiconductor memory device includes a clock latency that can be controlled responsive to whether or not an output order of burst data is reordered. The semiconductor memory device may comprise a control unit and a latency control unit. The control unit may generate a latency control signal having a logic level that varies depending on whether or not an output order of burst data is reordered. The latency control unit may control a latency value in response to the latency control signal. The semiconductor memory device and the method of controlling the latency value responsive to a reordering of the burst data allow for an optimally fast memory access time.
