Press Releases

Phison Electronics Corp., a worldwide leader in NAND controller and storage solutions, announces the shipment of 3D 64-Layer 4-bit per cell QLC NAND SATA solutions with its PS3111-S11T controller. “A QLC die doubles the density of the TLC. The successful launch of QLC-based products would mean a lot to the memory industry,” said KS Pua, Chairman and CEO of Phison, “SSDs are becoming more affordable with larger capacities than ever.”

  Mr. Pua notes that the release of the next generation 3D 64-Layer QLC NAND Flash has been pulled-in by about a quarter.  This has taken the industry by surprise and we have to thank the NAND manufacturers’ technology advancements for that. With this trend, the market penetration of SSDs are expected to accelerate. Phison is proactively taking the lead in enabling the QLC for a series of controllers, starting with the PS3111-S11T + QLC SATA SSD solution.

     The new 3D 64-Layer QLC NAND has a mono die density of 128GB. Powered by the PS3111-S11T controller, the SSD solution has capacities of 256GB~1TB. Phison’s 4th generation SmartECC™ engine exceeds the standard QLC controller requirements and provides outstanding performance for client SSDs.
