ABSTRACT:
The invention relates to an SRAM memory cell, a memory cell arrangement and a method for fabricating a memory cell arrangement. The SRAM memory cell has six vertical transistors, of which four are connected up as flip-flip transistors and two are connected up as switching transistors, four of the vertical transistors being arranged at corners of the rectangular base area.
