In this paper, we demonstrate nondestructive readout memory characteristics of a bistable resistor (biristor) with an n
+ -p-n+ Si nanowire (SiNW) channel on a bendable substrate. The SiNW channel is fabricated using a top--down route, which is compatible with the current complementary metal-oxide-semiconductor technology. The SiNW biristor shows the outstanding memory characteristics such as a retention time of 10 s and a current sensing margin of ~23-μA at room temperature. These memory characteristics originate from a positive feedback process resulting from impact ionization near the p-n junction. Moreover, the positive feedback mechanism is comprehensively investigated using device simulation. [ABSTRACT FROM AUTHOR]- Published
