    摘要: In a power on reset (POR) circuit, when power is turned on, an output signal of an inverter attains an H level and an N channel MOS transistor is rendered conductive. The potential of an input node of the inverter becomes a potential of a power supply voltage divided by a conductive resistance value R1 of a P channel MOS transistor and a conductive resistance value R2 of an N channel MOS transistor. Assuming that the threshold voltage of the inverter is 0.8 V and R1:R2=2:3, then the power supply voltage Vres at the time when signal POR# inverts its level becomes 1.33 V. Thus, this POR circuit can reliably be utilized even in a product designed to operate with 1.5 V incorporating a MOS transistor having a threshold voltage of 0.8 V.

    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.
