This course covers device and circuit technologies for memory systems that play an essential role in logic systems such as microprocessors, system-on-chip (SOC) devices, field-programmed gate array (FPGA) devices, and microcontrollers. First, the instructor lectures on the organization of hierarchical memory systems, circuit technologies of memory subsystems using various memories. Second, fundamentals of CMOS circuits are briefly reviewed, and then students learn the operating principles of bistable circuits as a basis for CMOS-based memories. Third, students will gain an understanding of the details of various flip-flop and SRAM circuits, along with their applications for registers, register files, and caches. Fourth, the instructor will cover device and circuit technologies of large capacity memory DRAM. Finally, practically used nonvolatile memories, i.e., Flash and FeRAM, and emerging nonvolatile memories such as MRAM, ReRAM, and PRAM are discussed. The present status and future prospects of these memory devices and circuits are also discussed.
