    摘要: A semiconductor integrated circuit with integrated memory and data-processing logic portions is provided, with which productivity and yield can be improved. The semiconductor integrated circuit is provided with a memory, a plurality of logic portions that are capable of being connected to the memory, and a separation portion that connects one of the plurality of logic portions to the memory, while separating the other logic portions from the memory. One required logic portion of the plurality of logic portions is connected to the memory, and the other non-required logic portions are separated from the memory, by the separation portion. The semiconductor integrated circuit can be switched for a system LSI after wafer processing, so this enables a plurality of system LSIs to be manufactured using the same exposure masks, thus improving productivity. Furthermore, defective logic portions can be recovered, thus improving the yield.

    摘要: A plurality of information memory cells and a single reference memory cell are coupled to a single word line. The reference memory cell stores reference information equivalent to a reference potential to information readout. Pieces of information, stored in the information memory cells, are fed, over respective bit lines, to first input terminals of sense amplifiers. The reference information, stored in the reference memory cell, is fed, over a bit line, to second input terminals of the sense amplifiers. When the potential of signal charges stored in the information memory cells falls due to leakage current, the potential of a signal charge stored in the reference memory cell correspondingly falls due to leakage current. This prolongs a length of time taken for a difference between these potentials to reach a sense limit, thereby achieving a longer data retention time. As a result of such arrangement, even when there occurs a small current leakage from memory cells, it is possible to secure a long data retention time thereby making it possible to obtain a long refresh cycle period.

    摘要: In a dynamic random access memory (DRAM), first and second output transistors form an NMOS-type tristate output buffer. Interposed between a gate electrode of the first output transistor and a data input/output terminal (DQ terminal) is an auxiliary transistor of which gate electrode is grounded and of which threshold voltage is lower than that of the first output transistor. Further interposed between the DQ terminal and a gate electrode of the second output transistor is another auxiliary transistor of which gate electrode is grounded and of which threshold voltage is lower than that of the second output transistor. Both auxiliary transistors lower gate voltages of both output transistors down to a negative voltage level such that both output transistors are maintained as cut off when a negative voltage is externally applied to the DQ terminal at the time of high impedance.
