A capacitorless 1T-DRAM technology using gate-induced drain-leakage (GIDL) current for low-power and high-speed embedded memory

A capacitorless one-transistor (1T)-dynamic random-access memory (DRAM) cell using gate-induced drain-leakage (GIDL) current for write operation was demonstrated. Compared with the conventional write operation with impactionization (II) current, the write operation with GIDL current achieves power consumption that is lower by four orders of magnitude and a write speed within several nanoseconds. The capacitorless 1T DRAM is the most promising technology for high-performance embedded-DRAM large-scale integration.
