➀ Kioxia Corporation and Nanya Technology have developed a low-power DRAM technology called OCTRAM, which uses oxide-semiconductor transistors for ultra-low leakage and high efficiency. The technology aims to significantly reduce power consumption in AI, post-5G communication, and IoT devices. ➁ The OCTRAM features a cylindrical-shaped InGaZnO vertical transistor as its cell transistor, offering enhanced memory density. ➂ The technology achieves a high 'on' current exceeding 15μA per cell and an 'off' current as low as 1aA per cell, reducing energy leakage to negligible levels.
