TSMC introduced its 40 nm RRAM platform in 2019. The 22 nm RRAM now represents the second generation of eRRAM, integrating advanced 22 nm CMOS technology and rivaling embedded Spin-Transfer Torque Magnetic RAM (STT-MRAM). The eRRAM boasts a memory block density of 17.5 bits/µm², with a 170 nm width in the bit-line direction. The RRAM storage layers are positioned on metal 3, optimizing space and performance by utilizing resistance for data switching.

ReRAM stands out among emerging memory technologies, including STT-MRAM, Ferroelectric RAM (FRAM), and Phase-Change Memory (PCM), as a strong contender to replace embedded flash (eFlash). Key benefits include high resistance to radiation, making it ideal for harsh environments, and maintaining functionality in high electromagnetic fields. Unlike charge-based devices, ReRAM avoids leakage problems, ensuring reliability.

The TSMC 22ULL eRRAM chip signifies rapid advancements in memory technology, promising enhanced performance and reliability for next-generation IoT devices. Solutions like ReRAM are poised to play a crucial role in the future of electronics.
