RRAM memory emulates synaptic plasticity

The human brain’s synapses—which send signals between neurons—can strengthen or weaken due to increases or decreases in activity. In the future, it may be possible to reproduce synaptic plasticity with RRAM memory run by specific coding schemes. A team of researchers from Leti, List, Clinatec, and INSERM investigated the topic, presenting a paper at IEDM 2016 in San Francisco.

The system could adapt to a range of plasticity mechanisms on time scales from several milliseconds to several months. In biology, where signals are very noisy, for example, short-term plasticity could ensure robustness in noisy environments; long-term plasticity could help monitor the progress of physiological processes. The innovation could aid in the development of smart implantable prosthetics.
