Course description and aims

This course provides device and circuit technologies for memory systems that play an essential role for logic systems such as microprocessors, system-on-chip (SOC) devices, field-programmed gate array (FPGA) devices, and microcontrollers. Firstly, requirements and organizations of hierarchical memory systems, circuit technologies of memory subsystems, and introduction of various memories are lectured. Secondly, fundamentals of CMOS devices and circuits are briefly reviewed, and then operating principles of bistable circuits are learned as a basis of CMOS-based memories. Thirdly, details of various flip-flops and SRAM cells are comprehended with their applications of registers, register files, and caches. Architectures for high speed, low-power, and stable operations for these memories are also discussed. Fourthly, device and circuit technologies of large capacity memory, that is, DRAM, is provided. Finally, practically used nonvolatile memories, i.e., Flash and FeRAM, and emerging nonvolatile memories, such as, MRAM, ReRAM, and PRAM, are discussed with new applications of nonvolatile memories for logic systems.
