Challenges and Trends of Memory Circuit Designs for Energy-Efficient IoT Devices

Memory has become one of the bottlenecks in the development of IoT and wearable devices with low energy consumption. This seminar addresses trends in the development of on-chip (embedded) volatile and nonvolatile memory (NVM) for energy-efficient IoT applications. In the first part, this talk will examine the challenges and trends in achieving low-voltage operation for embedded SRAM. Then, this talk will review silicon-verified circuit techniques for low-VDD SRAMs. The 2nd part of this seminar will introduce a variety of nonvolatile memory (NVM) technologies, including ROM, Flash, resistive RAM (ReRAM), phase-change memory (PCM), and STT-MRAM. This seminar will explore the challenges and silicon verified solutions in the design of low-power and high-speed circuits for on-chip NVM macros.
