    摘要: A back bias generator for a semiconductor device improves refresh characteristics, reduces leakage current, and increases back bias supply capacity in a DRAM having a triple well structure by applying a well bias voltage to the bulk of an NMOS transfer transistor. The back bias generator includes a well bias generator that generates the well bias voltage before the pumping voltage is applied to the transfer transistor. The well bias provides a back bias to a parasitic NPN transistor formed in the triple well of the NMOS transfer transistor, thereby preventing leakage through the NPN into the substrate. The well bias is also applied to the bulk of a clamp transistor that initializes a pumping capacitor.

    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.

    摘要: An internal power control circuit for a semiconductor device allows easy testing of the internal circuit blocks or memory arrays at various voltage levels. In the semiconductor device, internal voltage switching circuits connected between the internal power supply line and each array power supply line are switched ON or OFF according to signals applied to control pads coupled to each internal voltage switching circuit. During normal operation, a power voltage generated by the internal voltage generator is applied through an internal power supply line to each array power supply line coupled to the internal circuit blocks. During a test operation, different power voltages may be applied to the control pads to selectively decouple individual array power supply lines from the internal power supply line, and selectively couple the power voltages applied to the control pads to the corresponding array power supply lines and internal circuit blocks.

    摘要: Multi-bank integrated circuit memory devices include a plurality of banks of memory cells that are divided into pairs of sub-banks of memory cells. The sub-banks of memory cells are arranged in a plurality of rows and columns of sub-banks of memory cells. The pairs of sub-banks extend diagonally relative to the plurality of rows and columns of sub-banks of memory cells. The pairs of sub-banks of the respective banks preferably are adjacent one another and extend diagonally relative to the plurality of rows and columns of sub-banks of memory cells. By providing diagonally extending sub-banks, the row address lines that extend between respective sub-banks of each bank may occupy reduced area. More specifically, row address lines that extend between pairs of sub-banks in same adjacent rows and same adjacent columns can cross over one another to thereby allow reduced area.

    摘要: A signal generator produces enable signals for bitline sense amplifiers in a semiconductor device. The signal generator includes a first driving element for producing a first enable signal at a first output line in response to first and second control signals, a second driving element for producing a second enable signal at a second output line in response to inverted signals of the first and second control signals, and an equalizing element connected between the first output line and the second output line for equalizing the first and second output lines in response to a third control signal. A control signal generating element generates the first, second, and third control signals, and inverted signals thereof, in response to predetermined input signals. The DC current generated from an output driver and the charging and discharging current of output loading can be reduced, to thereby reduce power consumption. Also, when the output signals are applied as enable signals of bitline sense amplifiers, an initial invalid sensing the bitline sense amplifier circuits can be avoided.
