History

Phison was founded in 2000 by Datuk Pua Khein Seng and four others. Phison claims to have produced the earliest single-chip USB flash removable disk, dubbed a "pen drive." In early October 2014, security researchers Adam Caudill and Brandon Wilson publicly released source code to a firmware attack against Phison USB controller ICs. This code implements the

(non-volatile memory express) solid-state drives (SSDs). With such technology, the chips built on the NVMe SSDs have read and write speed of up to 7,000 MBs per second. In late 2020, Phison started shipping their E18 for high-end NVMe SSDs. In January 2021, Phison announced that they were planning to introduce a pair of USB flash drive controllers for high-end portable SSDs, designed to compete against current solutions that combine a USB to NVMe bridge chip with a standard NVMe SSD controller. Phison also released a new entry-level DRAM-less NVMe SSD controller in 2021. For portable SSDs, Phison introduced the U17 and U18 controllers. For NVMe SSDs, Phison introduced the E21T controller in 2021, their latest DRAM-less NVMe controller. This is a follow-up to the E19T controller, which had seen very little use in retail consumer SSDs but has actually been outselling their high-end E16 PCIe 4.0 controller due to strong demand from OEMs. In January 2022, Phison introduced the E26 SSD controller, with higher transfer speeds than previous controllers. In April 2022, Phison announced a long term partnership with data storage company Seagate to develop and distribute enterprise NVMe SSDs.
