YMTC’s New In-House Controllers to Power PCIe 4.0 SSDs

Posted on

All leading makers of 3D NAND memory have their in-house developed controllers for solid-state drives that power their own-brand SSDs. Being a considerably smaller 3D NAND manufacturer, Yangtze Memory Technologies Co. is following in the steps of its larger rivals by designing its own SSD controllers. Recently two of these controllers passed PCI Express compliance validation at a PCI-SIG workshop.

YMTC’s family of PCI-SIG-validated SSD controllers currently include models PE310 and PE320, though there may be other controllers that are not listed in the PCI-SIG Integrators List. Both controllers feature a PCIe 4.0 x4 host interface and are designed for higher-end drives. Since both chips have the same host interface, we can speculate that they support a differing number of NAND flash channels.
