SK Hynix and AMD had been on the forefront of the reminiscence business with the primary technology of excessive bandwidth reminiscence (HBM) again in 2013 – 2015, and SK Hynix remains to be main this market by way of share. In a bid to keep up and develop its place, SK Hynix has to adapt to the necessities of its clients, significantly within the AI area, and to take action it is mulling over how you can make ‘differentiated’ HBM merchandise for big clients.

With HBM4, the reminiscence is ready to transit to a 2048-bit interface, which is able to guarantee regular bandwidth enchancment over HBM3E.

However there are clients which can profit from differentiated (or semi-custom) HBM-based options, based on the vice chairman.

Given the corporate’s huge expertise with HBM, it might nicely give you one thing else, particularly for differentiated choices.
