摘要

This report introduces the cryogenic operation and storage performance of 3-D flash memory. The cell transistor characteristics and the basic functionalities, including read and program and erase (P/E) operations, are investigated at an extremely low temperature of 77 K cooled by the liquid nitrogen. The cell transistor has a steep subthreshold slope at 77 K compared with at 300 K, and the read op...
