    摘要: The read/write circuit comprises a data output buffer (DOB) connected through a three-state circuit (Qa, Q b ) to a common data input/output terminal (I/O), and a data write-in buffer (DWB) of a dynamic type having a latching function connected between the common data input/output terminal (I/O) and data buses (DB, DB) for providng latched data to the data buses. By utilizing a rise or a fall of a write enable signal (WE) or a column address strobe signal (CAS) applied to the memory device, the three-state circuit (Qa, Q b ) is set to a high impedance state, and then write data is latched into the data write-in buffer (DWB).

    摘要: A dynamic random access memory device comprises one-transistor, one-capacitor-type memory cells (Coo - C 127.127 ) in rows and columns and dummy cells (DC20'~ DC 2,127 , DC 20 " ~ DC 2.127 ", DC20'" ~ DC 2,127 "') in rows. The capacitors (C d ) of the dummy cells are charged to a high power supply potential (V cc ) by one or more charging transistors (Q A , QA') clocked by a reset clock signal (0R). The capacitors (C d ) of the dummy cells are discharged to a low power supply potential (V ss ) by one or more transistors (Q B , Q B ') clocked by an operation clock signal (⌀ WL ) having a potential lower than the high power supply potential (V cc ).

    摘要: An IC semiconductor device includes a bias-voltage generator comprising an oscillator (OSC), a charge-pumping circuit which is driven by the oscillator via a pumping capacitator, and a charge-pumping switch (41). The charge-pumping switch (41) is connected in series with the charge-pumping circuit. The charge-pumping switch is operated by an external electrode (PAD). The charge-pumping switch is turned OFF by the external electrode substrate leak circuit when measurement of substrate leak current is to be carried out, thereby enabling greater accuracy of measurement.

    摘要: A semiconductor memory device comprises a sense amplifier (1) formed on a semiconductor substrate (10), paired bit lines (BL) connected to the sense amplifier and memory cells (MC) connected to the bit lines. A predetermined bias voltage is applied to the semi-conductor substrate, and a reading operation is performed by amplifying, by means of the sense amplifier, a voltage difference produced between the paired bit lines due to accessing the memory cells. A voltage of reverse phase relative to noise on the bias voltage applied to the substrate is fed to the semiconductor substrate via a capacitance (21 formed on the substrate, to cancel the noise. By virtue of this feature, the influence of such noise can be minimised in the semiconductor memory device of the present invention.
