Advanced computing RAM for enhanced artificial intelligence applications

This technology is a digital in-memory random-access memory (SRAM) architecture that enhances the computational time and resiliency for computational neural networks use in artificial intelligence (AI) applications.

Unmet Need: Computer memory architectures which can withstand the demands of artificial intelligence

The implementation and use of artificial intelligence (AI) in electronics and computing is expected to revolutionize numerous industries and experience exponential growth and demand. Current computational architecture systems to run convolutional neural networks and AI algorithms can be extremely taxing to the system, resulting in severe energy losses and heat buildup. This can damage the computer systems and also generation life-threatening situations if failure occurs in applications such as autonomous vehicles and medical devices. Advanced computational systems are urgently needed to handle process, voltage, and system fluctuations which are encountered with AI systems.
