At FMS 2019, Phison shared the specifications for its future generation of customer SSD controllers. The PS5018- E18 premium controller will certainly be used a FinFET procedure modern technology as well as assures to improve consecutive read as well as create efficiency of drives to 7 GB/s. The PS5019- E19 T conventional controller will certainly be a fast follow-up to the E13 T that is presently in manufacturing yet has actually not yet delivered in retail items.
With its PS5016- E16 chip, Phison was the very first to present customer SSD controllers with a PCIe 4.0 x4 user interface as well as is presently appreciating its one-of-a-kind setting on the marketplace. The PS5016- E16 is basically an upgrade of the PS5012- E12– still including 2 Arm Cortex- R5 cores, 8 NAND networks ranked at 800 MT/s as well as used TSMC’s 28 nm procedure modern technology, and now including a PCIe 4.0 x4 PHY as well as improved mistake adjustment abilities. In the coming months, Phison’s entry-level NVMe controller will certainly obtain a comparable follower: the brand-new PS5019- E19 T will certainly be based upon the PS5013- E13 T (one Arm Cortex- R5 core, 4 NAND networks, 28 nm modern technology), yet including a brand-new PCIe 4.0 x4 PHY as well as therefore allowing cost-efficient yet quick SSDs.
Phison’s next-generation PS5018- E18 premium customer SSD controller with a PCIe 4.0 x4 user interface will certainly be dramatically various from the present E16 The chip gets a 3rd Arm Cortex- R5 core, NVMe 1.4 conformity, enhanced equipment protection formulas, as well as will certainly be used TSMC’s 12 FFC manufacture procedure.
The crucial renovation in the brand-new controllers is assistance for faster NAND user interface rates of as much as 1200 MT/s. This is required to obtain complete efficiency out of 96 L as well as more recent 3D NAND. For the premium E18 this permits the controller to really supply two times the throughput of any kind of PCIe 3.0 x4 drive, where the E16 can just make use of a portion of the additional transmission capacity supplied by the PCIe 4.0 upgrade. The quicker NAND user interface additionally permits the E19 T to strike consecutive rates that are somewhat faster than a PCIe 3.0 x4 web link can take care of, regardless of the E19 T having just 4 NAND networks rather than the 8 networks made use of by premium NVMe controllers.
Peak power intake for both the E19 T as well as E18 will certainly be greater than for their particular precursors, yet that’s since they are a lot quicker; the more recent controllers will really be much more reliable.
Phison’s cubicle at FMS consisted of real-time demonstrations of the E13 T, E19 T as well as E16 controllers, yet the E18 controller was not present. The low-end E19 T controller will certainly be tasting by the end of the year as well as is most likely to turn up in retail drives by the end of Q12020 This implies that the E13 T is most likely to be extremely short-term in the retail market. The premium E18 will certainly be getting here a little bit later on, tasting in Q1 2020 as well as striking the racks in Q3, a year after the E16 it changes.
