    摘要: A supply instruction signal attains the H-level before data is written into a plurality of memory cells. A P-channel MOS transistor is arranged between a power supply node and an input node. The P-channel MOS transistor is turned off to open the input node according to the supply instruction signal. In this case, a write driver discharges electric charges accumulated on the input node and electric charges accumulated on a bit line pair. However, a through-current does not flow from the power supply node to a ground node so that flow of the through-current to a CMOS inverter circuit forming each memory cell can be prevented. Accordingly, such a static semiconductor memory device can be provided that can prevent the flow of the through-current to the CMOS inverter circuit forming each memory cell when simultaneously writing data into the plurality of memory cells.

    摘要: A control circuit generates burn-in test signals and a signal on the basis of an address for causing transition of a semiconductor memory device to a burn-in test mode to output the signals to a predecoder. The predecoder outputs signals for selecting even-numbered word lines and signals for causing odd-numbered word lines to be in a non-selected state on the basis of the burn-in test signals at H level and further outputs signals for causing even-numbered word lines to be in a non-selected state and signals for selecting odd-numbered word lines on the basis of the burn-in test signals at H level. As a result, stresses can be effectively applied by the burn-in test.

    摘要: To obtain a semiconductor memory device capable of keeping the internal circuit in active state at all times, without increasing the power consumption during normal operation, and not increasing the number of pins. A burn-in clock generating circuit (1) receives an external clock CLK, a mode signal MODE, and an internal clock INTCLK to output a burn-in clock BICLK to a decoder (5). The burn-in clock BICLK becomes a signal equivalent to the internal clock INTCLK when the mode signal MODE is a fixed signal of H or L indicating normal operation, and becomes a fixed signal of H for indicating activation at all times when the mode signal MODE is a clock at half frequency of the external clock CLK.

    摘要: A delay circuit delays an internal write control signal by a prescribed time to a global write driver. The global write driver is enabled in response to the delayed write control signal received from the delay circuit, to drive a global write data bus in accordance with internal write data from an input buffer. A block write driver is enabled in response to an internal write control signal and a block selection signal, to drive a local write data bus in response to data on the global write data bus. A write gate connects a bit line to the local write data bus in response to a column selection signal. The delay circuit sets the output of the block write driver at a low level for a prescribed period, whereby a precharge potential of the bit line is reduced to reduce the potential amplitude of the bit line in data writing. An SRAM which operates at a high speed with an enlarged write recovery time margin is provided. SRAM also includes various arrangement for improving operating characteristics and reliability.

    摘要: A semiconductor memory comprising a flip-flop circuit, a redundant memory cell row and column, a specific address detecting gate, a transistor, a sense amplifier and a data output buffer. The receipt of a supply potential causes the flip-flop circuit to generate previously stored output status representing the use or the nonuse of the redundant memory cell row and column. Upon detection of a specific address by the specific address detecting gate, the transistor effects a switching operation causing the output status generated by the flip-flop circuit to be output to the outside via the transistor, sense amplifier and data output buffer. This allows the use or the nonuse of the redundant bits to be verified efficiently.

    摘要: An ECL buffer circuit includes an input portion for receiving an input signal at an ECL level, a current switch portion and an output portion. The input portion includes a bipolar transistor (Q1), a level-shift diode (D1) and a constant current source (CS1). The current switch portion includes a first and a second switch circuits and a constant current source (CS2). Each switch circuit includes a resistor (R1, R2) and a bipolar transistor (Q2, Q3). The output portion includes a first and a second output circuits and a constant current source (CS3). Each output circuit includes an emitter follower transistor (Q4, Q5) and a bipolar transistor (Q6, Q7). The first output circuit receives an input signal from the input portion, and the second output circuit receives a reference voltage (V.sub.BB). A by-pass resistor (R3, R4) is connected between the base and the emitter of an emitter follower transistor (Q4, Q5) of each output circuit. When the output signal changes from a second level to a first level, the output signal thereby rapidly changes to a predetermined voltage by the emitter follower transistor (Q4, Q5) at first, then changes to a first level by way of the by-pass operation of the by-pass resistor (R3, R4).
