From CMOS to Memristor Nanoelectronics: Search for Best Design Threading
University of California, Santa Cruz, US
University of Michigan, Ann Arbor, US
Since the 1970s, CMOS technology-based circuits and systems have revolutionized the microelectronics industry, in analog, digital and mixed signal fields. From the start, CMOS technology has overcome formidable competition from NMOS, bipolar, GaAs and other compound semiconductor technologies. The forceful advancement of CMOS technology has been empowered by advantages mainly in low power consumption and ease of design. However, single-digit feature sizes in CMOS nanotechnology downscaling face insurmountable roadblocks, such as fabrication limits, prohibitive costs, and limited dependability on the electrical charge quantity in high-density circuits. To highlight the challenges of commercialization, Global Foundries opted to bow out of the scaling race at the 7 nm node. Since HP’s announcement of nanoscale memristor fabrication in 2008, memristor technology has risen to be a strong companion technology to CMOS, by providing programmable resistance states in lieu of less-reliable charge storage.
The use of memristance (aka, memory resistance) can provide new means for reliable nanoscale memory design, instead of significantly less reliable charge variables in nanoscale DRAM or SRAM. For neuromorphic computing, crossbar arrays of memristors can compactly implement the weighted summation of input vectors, which is the core of CNN operations. It turns out that neuromorphic hardware can be implemented using memristors, which can parallelize a huge number of simple operations. This is precisely what is needed in the implementation of deep neural network accelerators with billions of parameters, making memristor-CMOS processing of neural networks superior over classical digital computers.
The first part of the talk will take a brief journey from the early stages of CMOS design to present memristor nanoelectronics with critical views and considerations for device threading, interconnect and circuit technologies for optimal system developments that achieve multidimensional design goals such as reliability, throughput performance, energy consumption, and manufacturing cost.
The second part of the talk will then apply these principles to neuromorphic systems, namely retina-inspired image processing and brain-driven computation. The powerful capabilities of these neuromorphic processors can be applied to a plethora of real-world challenges, from data-driven healthcare, to neurostimulation, and in AI-generated artwork, as we make a profound shift away from the sequential processing of Von Neumann machines towards parallel, interconnected neural-inspired structures.
