    Abstract: A semiconductor memory device that minimizes chip area is provided. The semiconductor memory device includes local input/output (I/O) lines, global I/O lines, and a memory core that is coupled between a bit line and a complementary bit line. The memory core includes a memory cell array, a bit line equalizer circuit, a PMOS sense amplifier (S/A), a PMOS S/A driving circuit for driving the PMOS S/A, a transmission gate circuit, an NMOS S/A, and an NMOS S/A driving circuit for driving the NMOS S/A.

The PMOS S/A driving circuit, which is a first driving transistor, and the NMOS S/A driving circuit, which is a second driving transistor, are also installed between adjacent bit lines. Because the semiconductor memory device arranges a PMOS S/A driving circuit, an NMOS S/A driving circuit, and a gating circuit for connecting local I/O lines to global I/O lines, between adjacent bit lines, the chip area is reduced.

    Abstract: An input buffer includes an amplifier circuit, such as a differential amplifier circuit, inverting amplifier circuit or pull-up/pull-down amplifier circuit. A momentary boost circuit is coupled to an input buffer input terminal, an input terminal of the amplifier circuit, and an output terminal of the amplifier circuit, and is operative to generate a boosted input signal at the input terminal of the amplifier circuit from an input signal at an input buffer input terminal for an interval that is terminated responsive to an output signal at the output terminal of the amplifier circuit. The momentary boost circuit may include a detector circuit coupled to the output terminal of the amplifier circuit and operative to generate a control signal responsive to a transition of the output signal, and a boost circuit, coupled between the input buffer input terminal and the input terminal of the amplifier circuit and operatively associated with the detector circuit, that receives the input signal at the input buffer input terminal and generates the boosted input signal at the input terminal of the amplifier circuit from the received input signal responsive to the control signal. For example, the boost circuit may include a capacitor coupled between the input buffer input terminal and the input terminal of the amplifier circuit, and a switch that couples and decouples the input terminal of the amplifier circuit to a reference voltage source responsive to the control signal. The detector circuit may be operative to generate a pulse responsive to a transition of the output signal, and the switch may be operative to couple the input terminal of the amplifier circuit to the reference voltage source responsive to the pulse.

    Abstract: A bidirectional input/output buffer operates in a current mode to increase the data transfer rate between devices connected by a bidirectional transmission line. The buffer includes an output current source for generating an output current responsive to a data output signal. The output current is combined with an output current indicative of a data input signal received from another device over a transmission line, thereby forming a mixed current signal. The data input signal is restored from the mixed signal by a restoring circuit that compares the mixed signal to a reference current that depends on the value of the data output signal. The restoring circuit includes a current mirror and a reference current source that generates a reference current in response to the data output signal. To provide additional performance, an embodiment of a bidirectional input/output buffer utilizes a switchless structure having two comparators that compare the mixed signal to two different reference signals, thereby generating two comparison signals. A selector circuit selects one of the two comparison signals as the restored data input signal responsive to the data output signal.
