How We Found the Missing Memristor

The memristor—the functional equivalent of a synapse—could revolutionize circuit design

Because memristors behave functionally like synapses, replacing a few transistors in a circuit with memristors could lead to analog circuits that can think like a human brain.

It’s time to stop shrinking. Moore’s Law, the semiconductor industry’s obsession with the shrinking of transistors and their commensurate steady doubling on a chip about every two years, has been the source of a 50-year technical and economic revolution. Whether this scaling paradigm lasts for five more years or 15, it will eventually come to an end. The emphasis in electronics design will have to shift to devices that are not just increasingly infinitesimal but increasingly capable.

Design for Functional Safety & Reliability with new FMEDA Database

Component Reliability Database drives efficiency and accuracy in FMEDA results

Design for Functional Safety & Reliability with new FMEDA Database

Failure Modes, Effects, and Diagnostics Analysis (FMEDA) is popular for predicting safety and reliability during design. FMEDA results, however, are only as good as the failure rate data used in the calculations. A new component reliability database (CRD) improves accuracy, reduces engineering, identifies unforeseen failure modes, and enables better decision-making.
