With the soaring price of custom electronics at advanced technology nodes, reconfigurable electronics are becoming even more important. In reconfigurable electronics, versatile architectures allow customized functions to be bound after fabrication. This paradigm of software-definable hardware offers intriguing benefits that include flexibility through in situ reprogrammation, fault tolerance through circumlocution, and rapid response solutions to be formed by configuring pre-built components. The penultimate example in current practice is the field programmable gate array (FPGA), which has evolved from being a curiosity to a multi-billion dollar disruptive technology. Phase change materials have not traditionally played a role in reconfigurable electronics, but offer powerful advantages by virtue of their non-volatility, durability, and the possibility of multi-state configurations. These concepts lead potentially to more compact computation architectures based on threshold logic, or more ambitiously dense arrays of artificial neurons and other novel hybrid (digital plus analog) signal processing architectures.
