摘要： A first capacitor is charged by a constant current source circuit for a time corresponding to the delay time of forward pulses. A second capacitor is charged by a constant current source circuit. A comparator compares the voltages of the first and second capacitors, and outputs a timing signal when these voltages match. For this reason, a timing at which the second capacitor has been charged for a time corresponding to the delay time of backward pulses can be obtained.

摘要： A first delay line for forward pulses and a second delay line for backward pulses are composed of unit delay elements. A state holding section determines the input position of a backward pulse on the second delay line according to the transfer position of a forward pulse transferred along the first delay line. In the unit delay elements constituting the first and second delay lines, the accuracy of synchronization can be improved by increasing the current driving capability of the transistors related to the rising of the pulse signal.

摘要： First transistors for charging respective one side nodes of a plurality of capacitors are connected to these nodes of the capacitors, respectively. Second transistors for outputting electric charge of each capacitor are connected between respective one side nodes of the capacitors and an output terminal, respectively. A plurality of third transistors for transferring the electric charge of the other side nodes of the capacitors to the other nodes are connected to the respective other nodes. The electric charge of each capacitor is serially transferred from nodes of a high electric potential to nodes of a lower electric potential through one path by sequentially controlling the third transistors, or the electric charge of each capacitor is parallel transferred between arbitrary nodes of a high electric potential and low nodes through a plurality of paths. By these operations, electric charge of each capacitor is recycled.

摘要： In a semiconductor memory device, charge transfer gates and a bit line precharging/equalizing circuit are inserted in the order mentioned in a bit line pair between memory cells and a sense amplifier. When the transfer gates are off, data of the memory cells are read out to the bit line pair located on the memory cell side. Subsequently, when the transfer gates are turned on, the data are transferred to the bit line pair located on the sense amplifier side. Thereafter, the transfer gates are turned off on the basis of a threshold value of the transfer gates. Then, the memory cell data transferred to the sense amplifier side are amplified by a conventional DRAM method. The bit line precharging/equalizing circuit does not require a large area. It is therefore possible to miniaturize the semiconductor memory device.
