Neuromorphic Analog Chips

"Chip designer mimicking brain, backed by Sam Altman, gets $25 mln funding":

Rain Neuromorphics Inc., a startup designing chips that mimic the way the brain works and aims to serve companies using artificial intelligence (AI) algorithms, said on Wednesday it raised $25 million.

 Gordon Wilson, CEO and co-founder of Rain, said that while most AI chips on the market today are digital, his company's technology is analogue. Digital chips read 1s and 0s while analogue chips can decipher incremental information such as sound waves.
