    摘要: A semiconductor memory device having a 3D stacked structure includes: a first semiconductor area with a stacked structure of a first layer having first data and a second layer having second data; a first line for delivering an access signal for accessing the first semiconductor area; and a second line for outputting the first and/or second data from the first semiconductor area, wherein access timings of accessing the first and second layers are controlled so that a first time delay from the delivery of the access signal to the first layer to the output of the first data is substantially identical to a second time delay from the delivery of the access signal to the second layer to the output of the second data, thereby compensating for skew according to an inter-layer timing delay and thus performing a normal operation. Accordingly, the advantage of high-integration according to a stacked structure can be maximized by satisfying data input/output within a predetermined standard.

    摘要: A semiconductor memory device achieves high speed operation while operating at a low power supply voltage by boosting the voltage level at the plate node of a memory cell during an access operation. The memory device includes a plate voltage generator which generates a variable voltage level. The plate voltage generator includes a pair of switches for coupling the plate node to either a conventional (1/2)VCC voltage generator or a power supply node in response to a control signal. The plate voltage generator also includes a pulse generator that generates a pulse signal for controlling the switches in response to the control signal. During a precharge period, the bitline pair is charged to VCC. The plate voltage generator charges the plate node to (1/2)VCC during the precharge state and then to VCC during an access operation. This boosts the voltage level at the storage node of the memory cell, thereby decreasing the time required to amplify the signals on the bitlines.

    摘要: Integrated circuit memory devices include at least first and second memory cells electrically coupled to respective first and second sense bit signal lines of a sense amplifier. The sense amplifier comprises a circuit for amplifying a difference in potential between the first and second sense bit signal lines by driving these lines to respective first and second different potentials. A driving circuit is also provided for simultaneously driving the first and second sense bit signal lines towards the first potential in response to application of a boost control signal. This driving circuit preferably comprises a first capacitor electrically connected in series between the boost control input and the first sense bit signal line and a second capacitor electrically connected in series between the boost control input and the second sense bit signal line. The boost control signal is established at the first potential to drive both the sense bit signal lines from different intermediate potentials (e.g., 1/2VCC+, 1/2VCC) towards the first potential, prior to amplification of the difference in potential between the first and second sense bit signal lines by the sense amplifier. The present invention enables the sense amplifier to operate in an environment where the power supply voltage (e.g., VCC) is reduced and the different intermediate potentials (e.g., 1/2VCC+, 1/2VCC) to be amplified are initially established at potentials below the normal sensitivity of the sense amplifier.
