Syllabus

Course overview and goals

Various memory devices have been implemented in digital integrated circuits depending on the speed or volume requirements. The lecture will include the memory hierarchy and its specification. The structure of each memory (SRAM, DRAM, Flash, FeRAM, MRAM, RRAM, PCRAM, etc.), its physical operation mechanism, and the peripheral circuits will be explained. In addition, recent development trends will be reviewed.

Course description and aims

Students who take the course will understand the memory hierarchy, its required specifications, and the memory operation principles of each device. They can assess which part of the hierarchy should implement the memory devices from the specification.

Keywords

memory system, memory hierarchy, SRAM, DRAM, Flash, FeRAM, MRAM, RRAM, PCRAM, peripheral circuits
