Abstract (en)

[origin: CN106062878A] A two-transistor memory cell based upon a thyristor for an SRAM integrated circuit is described together with methods of operation. The memory cell can be implemented in different combinations of MOS and bipolar select transistors, or without select transistors, with thyristors in a semiconductor substrate with shallow trench isolation. Standard CMOS process technology can be used to manufacture the SRAM.
