Crossbar’s ReRAM CMOS compatibility and scalability to small process geometries enables the integration of non-volatile memory IP blocks at the same process nodes of micro-controllers (MCU), System-on-Chip (SoC) and Field Programmable Gate Array (FPGA). RAM blocks based on SMIC’ 40nm CMOS manufacturing process are available now. This first partnership enables customers to integrate low latency, very high performance and low power embedded ReRAM memory blocks into MCUs and SoCs, targeting the Internet of Things, wearable and tablet computers, consumer, industrial and automotive electronics markets. Crossbar also has plans to port our technology to smaller process nodes for other applications.

Crossbar ReRAM cells are integrated at the Back-End-Of-Line of standard CMOS process between two metal lines of standard CMOS wafers with direct connections with the underneath CMOS logic IP blocks. This enables extremely integrated solutions with on-chip non-volatile memory, processing cores, analog and RF on a single die.

With the small incremental cost of two additional masks over standard CMOS process using very little foundry capital investment, and with superior memory performance and characteristics, Crossbar is providing a great value to the embedded Non-Volatile Memory (eNVM) applications.

The versatility of Crossbar’s ReRAM technology opens the possibilities to innovative memory and storage solutions that can be directly integrated with state-of-the-art processing logic cores: better energy efficiency by improving system performances and reducing the complexity of today’s block oriented Flash-based solutions.
