摘要： An energy-saving device for a memory circuit. The energy-saving device is capable of immediately terminating a local sense amplifier enable signal to a sense amplifier. The energy-saving device employs a plurality of Schmitt triggering circuits with each Schmitt triggering circuit capable of receiving an operational signal and an inverse operational signal and capable of issuing a Schmitt triggering signal to a data-transmission tester. The data-transmission tester will issue a response signal when change in the Schmitt triggering signal is detected. A data-transition-detected pulse is sent from a data-transmission-testing pulse generation circuit to a power shut down signaling circuit to terminate the local sense amplifier enable signal when the data-transmission-testing pulse-generation circuit receives a response signal.

摘要： A sense amplifier can be used with a high-speed IC memory device, which sense amplifier can help reduce the sensing latency during read operations to the memory device so as to allow fast access speed to the memory device. The sense amplifier includes a first-stage circuit, coupled to the bit lines of the memory device, for amplifying the differential data signal on the bit lines. Furthermore, a second-stage circuit has an input side coupled to receive the output signal from the first-stage circuit and an output side coupled to the bit lines, and is used for amplifying the output signal from the first-stage circuit and feeding the amplified signal back to the bit lines. The first-stage circuit and the second-stage circuit in combination constitute a positive feedback amplification loop coupled to the bit lines for amplifying the differential data signal on the bit lines to a detectable level. This positive feedback amplification loop allows the differential data signal on the bit lines to be quickly amplified to the detectable level with a reduced sensing latency, thus increasing the access speed to the associated memory device. Moreover, even though the bit lines are increased in length, the sensing speed is not significantly affected. This feature can also help save circuit layout space.

摘要： A sense/output circuit is designed for use with a memory device, such as an SDRAM (Synchronized Dynamic Random-Access Memory) device, which is capable of switching off some power-consuming circuit components immediately after the requested data output is completed. This feature can help reduce the power consumption by the overall memory system, making the use of the SDRAM device more cost-effective. Moreover, the reduction of power consumption can be achieved without concerning process parameters, component parameters, and temperature variations. As a result, the delay margin can be reduced compared to the prior art, which also contribute to the reduction of power consumption.

摘要： A method is proposed for eliminating signal skew in an SDRAM (Synchronized Dynamic Random-Access Memory) device resulting from the data signal being attenuated into different input signal amplitudes at the respective input points into the memory cells in the SDRAM device. The method is intended for use on a SDRAM device having at least a first memory cell and a second memory cell which are connected to a common signal line which transmits a data signal to both the first and the second memory cells. Due to the data signal being gradually attenuated along the signal line, the input signal amplitudes at the respective input points into the first and second memory cells are different, which would otherwise cause signal skew. In accordance with this method, the trigger voltage levels of the memory cells are adjusted in such a manner as to be substantially equal to the respective input signal amplitudes at a specific trigger time, so that all the memory cells can be triggered substantially concurrently without the occurrence of signal skew. Typically, the trigger voltage levels can be adjusted by adjusting the respective threshold voltages or current gains of the NMOS transistor and PMOS transistor in an inverter used as the I/O buffer of each memory cell. By this method, the adjustment can be easily achieved without having to provide additional circuitry to the SDRAM device. This method is therefore useful in solving the problem of signal skew in the SDRAM device.

摘要翻译： 提出了一种用于消除SDRAM（同步动态随机存取存储器）中的信号偏移的方法，该信号由数据信号衰减到各个输入点处的不同输入信号幅度，进入SDRAM器件中的存储单元。 该方法旨在用于具有至少第一存储器单元和第二存储器单元的SDRAM器件，该第一存储器单元和第二存储器单元连接到向第一和第二存储器单元发送数据信号的公共信号线。 由于数据信号沿着信号线逐渐衰减，所以进入第一和第二存储器单元的各个输入点的输入信号幅度不同，否则会导致信号偏移。 按照这种方法，存储器单元的触发电压电平被调节成基本上等于在特定触发时间的相应输入信号幅度，使得所有的存储单元可以基本同时触发，而没有 出现信号偏移。 通常，可以通过调整用作每个存储单元的I / O缓冲器的反相器中的NMOS晶体管和PMOS晶体管的相应阈值电压或电流增益来调整触发电压电平。 通过这种方法，可以容易地实现调整，而不必向SDRAM设备提供额外的电路。 因此，该方法可用于解决SDRAM器件中的信号偏移问题。

摘要： A sense amplifier circuit for a semiconductor memory device. The sense amplifier of this invention has four more NMOS transistors than a conventional amplifier. The gate terminals of two of the NMOS transistors are connected to a write enable line. The gate terminals of the other two NMOS transistors are connected to a first and a second node point, which are in turn connected to a bit line and a complementary bit line, respectively. Through a feedback circuit provided by these four additional NMOS transistors, two of the NMOS transistors are switched on during a write cycle to provide a ground connection so that voltage level of the sense amplifier is rapidly pulled down. Since the latching speed of the sense amplifier is increased, the operating speed of the memory is increased, as well. In addition, partial writing of data can be avoided.
