With the acceleration of digital transformation, the integration of AI and Big Data is likely to create new values and to lead us towards an era of data-centric cloud, where large amounts of data is created, delivered and analyzed with unprecedented speed and accuracy. To enable such transformation and realize data-centric cloud, increasingly high speed, low power, high capacity, and high reliability memory semiconductors are required. Within the memory semiconductor industry, we have continued to overcome the technological challenges of DRAM scaling and NAND flash stacking by making continuous improvements. However, the pace of semiconductor technology development is yet to catch up with the rate at which data is produced, which necessitates still more innovative semiconductor technologies to handle the explosive growth in data. In this speech, I would like to introduce SK hynix's journey towards future data-centric era and also discuss next generation memory-centric system R&D directions to overcome the hurdles facing with data-centric cloud infrastructure.
