Phison Electronics Corporation was established in November 2000 in Hsinchu, Taiwan. Starting with the world's first single-chip USB flash drive IC, Phison is now the market leader in NAND Flash controllers and the private label manufacture of NAND storage devices with USB, SD, eMMC, PATA, SATA, PCIe and UFS interfaces. Annually the company ships over 600 million controllers worldwide and has topped US $1.5 billion dollars in sales revenue. As a NAND flash total solution provider, Phison also offers custom ASIC design and OEM/ODM services for partners.[1]

Phison has over 2000 employees and with the majority focused on engineering. The company strives to accelerate the adoption of NAND Flash technology across multiple industries and is a founder of Open NAND Flash Interface (ONFI) group as well as holding board seats on the SD and UFS Associations.

Phison’s competitive engineering and R&D teams have brought several products to market before competitors. This includes the first USB flash removable disk dubbed “Pen Drive”, in May 2001. Another industry first came in 2018 with the introduction of the PS5016-E16, the world’s first PCIe Gen4 NVMe SSD.[2]

In August 2019, Phison announced that they would be releasing PS-50 series chips that are designed to support PCIe 4.0 NVMe Solid State Drives. With such technology, the chips built on the NVMe SSDs have read and write speed of up to 7,000 MBs per second.[3]

Office Locations[edit]

Phison’s headquarters is located in Miaoli, Taiwan. The company has branch locations in San Jose, California, Penang, Malaysia, Shenzhen, China, Hefei, China, and Tokyo, Japan. Phison also maintains several sales offices around the globe.[4]  


Phison’s SSD product line divides into two groups consisting of SATA and NVMe over PCI Express.

The latest additions to the PCIe side include the E19T and E18[5], both utilizing the PCIe Gen4 specification. These follow the PS5016-E16[6], also known as the world’s first PCIe Gen4 SSD controller.

Prior to the E16, Phison also released the E13, E12[7], and E7[8] Series NVMe controllers utilizing the PCI Express Gen3 bus.

The company has a longer history of products utilizing the SATA bus. The most recent roadmaps show the S17T. This is the successor to the S13T[9] and S11T. The S10[10] flagship controller dates back to 2014 and has proven to be a resilient controller.  Its product life has spanned several generations of flash memory. Prior to the S10, Phison released the S8[11] and S6 Series products through partners.  

In 2019, Phison added design wins in the competitive DC (data center) product categories with the PS5012-E12DC and PS3112-S12DC. Major partners include Seagate[12] and Kingston[13] with both bringing DC products to market with Phison controllers.
