Hynix memory is used by Apple in some of their iMac, MacBook and MacBook Pro computers. Apple's A9 chipset is onboard together with an SK Hynix RAM module believed to be "likely the same 2 GB LPDDR4 mobile DRAM found in the iPhone 6s".[6] Hynix memory is also used by Asus in their Google-branded Nexus 7 tablet (both 2012 and 2013 models), an OEM provider for IBM System x servers, and is used in desktop PCs and laptops as well as the Asus Eee PC, Dell, HP Inc., and Hewlett Packard Enterprise (formerly Hewlett-Packard) have also used Hynix memory as OEM equipment.[2] Other products that use Hynix memory include DVD players, cellular phones, set-top boxes, personal digital assistants, networking equipment, and hard disk drives.[7]
