IBM Reveals 8-Bit Analog Chip With Phase-Change Memory

Today at the IEEE International Electron Devices Meeting in San Francisco, IBM reported a new 8-bit analog chip. But the true development was less about analog chips catching up to their digital peers and more a radical rethink of chip architecture. This chip is the first to perform 8-bit calculations right where information is stored. IBM’s new analog chip is based on phase-change memory. The key ingredient is a material that can undergo phase changes in response to electrical current.
