Semiconductor memory scaling and beyond

Semiconductor is an indispensible component of modern electronic systems. The history of the semiconductor industry is namely the history of scaling that has consequently benefited consumers by advancing the mobile era by providing high density product at low price. Besides, every semiconductor memory company is facing the ultimate physical limit of scaling. Natural question arising here is “What will be the next?”. As parts of efforts to overcome those limits and grasp new opportunities under new environment, where meeting requirements of power consumption and data bandwidth in addition to memory density is much more difficult while the importance of them is increasing, new technologies including 3D-IC and non-volatile new memories are currently being researched and developed.
