    摘要： A semiconductor static random access memory having a high .alpha.-ray immunity and a high packing density is provided which is also capable of high-speed operation. A semiconductor memory device comprises static random access memory cells each including a flip-flop circuit. Storage nodes of each flip-flop circuit have respective pn-junctions formed at regions sandwiched between gate electrodes of first insulated gate field effect transistors and gate electrodes of second insulated gate field effect transistors, respectively. The pn-junction has an area smaller than that of a channel portion of the first or second insulated gate field effect transistor. The gate electrode of one of the two first insulated gate field effect transistors and the drain region of the other insulated gate field effect transistor, on one hand, and the drain region of the one insulated gate field effect transistor and the gate electrode of the other insulated gate field effect transistor, on the other hand, are electrically cross-coupled mutually through first and second electrically conductive films, respectively. Also, to increase packing density and enhance immunity to soft error, the gate electrodes of the first and second insulated gate field effect transistors extend substantially in parallel with one another and the channel regions of the first and second insulated gate field effect transistors extend substantially in parallel with one another.

    摘要： Herein disclosed is a semiconductor integrated circuit device comprising a SRAM having its memory cell composed of transfer MISFETs to be controlled through word lines and drive MISFETs. The gate electrodes of the drive MISFETs and the gate electrodes of the transfer MISFETs of the memory cell, and the word lines are individually formed of different conductive layers. The drive MISFETs and the transfer MISFETs are individually arranged to cross each other in the gate length direction. The word lines are extended in the gate length direction of the gate electrodes of the drive MISFETs and caused to cross the gate electrodes of the drive MISFETs partially.The two transfer MISFETs of the memory cell have their individual gate electrodes connected with two respective word lines spaced from each other and extended in an identical direction. The region defined by the two word lines is arranged therein with the two drive MISFETs and the source lines.The source line is formed of a conductive layer identical to that of the word line. The individual data lines of the complementary data line are formed of an identical conductive layer which is different from that of the word line and the source line. The identical conductive layer between the word line and source line and the complementary data line is formed with two word lines: a main word line extended in the first direction identical to that of the word line and source line and used by adopting the divided word line system: and a sub-word line used by adopting the double word line system.
