According to the invention, a bipolar transistor whose collector is connected to a differential amplifier and which supplies a current to the differential amplifier in accordance with a signal which is inputted to a base or an emitter is added, and a bipolar transistor to supply a current only when writing to bit lines is connected. According to the invention, a high speed of the access time when information is read out by switching the selection bit line is accomplished. Further, the charge/discharge time of the bit line when information is written is reduced and a high speed of the writing time can be also accomplished.

    摘要: Disclosed is a static type memory cell with high immunity from alpha ray-induced soft errors. The memory cell has a coupling capacitance C.sub.c between two data storage nodes 1 and 2. The p-well (or p-substrate) in which the driver-MOS transistors MN3, MN4 and the transfer MOS transistors MN1, MN2 are formed is connected to a V.sub.bb generator. The voltage V.sub.bb is set lower than the low level V.sub.L of the memory cell signal potential. Even when the potential variation .DELTA.V.sub.L of the low-voltage side node 2 is large, the parasitic diode present between the n-type diffusion layer corresponding to the source or drain of MN1-MN4 and the p-well (or p-substrate) does not turn on. Erroneous operations can therefore be prevented.

    摘要: A semiconductor memory has a plurality of word lines a plurality of bit line pairs and a plurality of memory cells formed at intersection points between the word lines and the bit line pairs. A word decoder generates a word line select signal upon receipt of an address signal and a bit decoder generates a bit line select signal on receiving the address signal. A bit line load circuit receives a signal current from the applicable memory cell, a sense circuit detects an output signal from the bit line load circuit, and a bit line pull-down circuit and a bit line recovery circuit drives the applicable bit lines upon writing data to the memory cell in question. The bit line load circuit and the bit line recovery circuit include pMOS transistors whose drains are connected to the bit lines and whose gates are fed with a control signal, and diodes whose anodes are connected to a first power supply and whose cathodes are connected to sources of the pMOS transistors, the pMOS transistors and the diodes being furnished to each of the bit line pairs. The pMOS transistors are inhibited from conducting while the bit lines are being driven Low by the bit line pull-down circuit during a write cycle, and allowed to conduct during other periods including a read cycle. This constitution shortens the recovery time, implementing a high-speed SRAM with a shortened cycle time.
