SSD Controller
SK Hynix Cepheus
SK Hynix PCIe 3.0 x4, NVMe 1.3 TSMC 12nm FinFET 1 drive in database
The SK Hynix Cepheus is an in-house NVMe controller used in the SK Hynix Gold P31. It is built on TSMC's 12nm FinFET process and uses a dual-core ARM 32-bit Cortex-R CPU. The controller supports 4 NAND channels running at 1,400 MT/s with 4 chip enables, and is configured with DRAM cache enabled.
The Cepheus is a fully vertically integrated component — SK Hynix designs both the controller and the 128-layer 3D TLC NAND used alongside it in the Gold P31. This integration is cited by reviewers as a contributing factor to the drive's efficient power consumption.
