Speaker: Dr. Xiaobo Sharon Hu, University of Notre Dame
Host: Dr. Albert ChengData transfer between a processor and memory is a major bottleneck in improving application-level performance. This is particularly the case for data intensive tasks such as some machine learning applications. In-memory computing, where certain data processing is performed in memory, could be an effective solution to address this bottleneck. Consequently, compact, low-power, fast and non-volatile in-memory computing is highly desirable. This talk presents a cross-layer effort of designing in-memory computing modules based on ferroelectric FETs, an emerging, non-volatile device. An FeFET is made by integrating a ferroelectric material layer in the gate stack of a MOSFET, and can behave as both a transistor and a non-volatile storage element. This unique property enables area efficient and low-power finely integrated logic and memory. Novel circuits/architectures based on FeFETs to accomplish computing in memory, content addressable memory and crossbar arrays will be elaborated. Application-level benefits, particularly for machine learning, in comparison with other alternative technologies will be discussed.
