What Purui Semiconductor does

Purui Semiconductor (Shanghai) Co., Ltd., publicly listed on the Shanghai Stock Exchange STAR Market under ticker 688766, is a fabless integrated-circuit design house specializing in non-volatile memory and memory-derivative products. Founded in 2016 (with predecessor Wuxi Puya established in 2012) and headquartered in Shanghai's Pudong Zhangjiang High-tech Park, the company designs and sells four core product lines: SPI NOR Flash memory (512Kbit–1Gbit across L/H/U/N voltage series), EEPROM (2Kbit–4Mbit, I²C and SPI), PY32 Series 32-bit ARM Cortex-M0+/M4 microcontrollers, and analog products (notably VCM drivers and OIS for smartphone cameras). A KGD (Known Good Die) wafer-level service complements the catalog. All silicon is fabricated and packaged by third-party foundries under a fabless model.

The company's core technology is its proprietary SONOS (Silicon-Oxide-Nitride-Oxide-Silicon) process platform, supplemented by an ETOX (Embedded Tunnel Oxide) process for higher-density NOR Flash. These two platforms underpin industry-leading ultra-low-power performance, exemplified by the GS N Series 1.1V 6.5UJ/Mbit NOR Flash. Technology is extended into the MCU product line via a 'Memory+' strategy that combines SONOS-derived embedded non-volatile memory with ARM-based controllers to provide integrated storage-plus-control solutions.

Revenue is generated through B2B hardware sales of these ICs to brand manufacturers across smartphones, PCs and peripherals, home appliances, industrial control, automotive electronics, AIoT/wearables, and servers/communications. Named customers include Samsung, OPPO, vivo, Xiaomi, Lenovo, HP, Midea, Sony, Toshiba, Panasonic and Philips. Go-to-market combines direct sales offices in China (Shanghai, Shenzhen, Suzhou, Wuxi) and South Korea, representative offices in Germany, the UK, the USA and Japan, and regional distributor channels. FY2025 revenue was RMB 2.32 billion (+28.62% YoY), with R&D investment at 12.82% of revenue and a workforce in which R&D personnel represent over 55%. In November 2025 the company acquired a 51% stake in Zhuhai Nuoya Changtian Storage Technology, consolidating Skyhigh Memory Limited (SHM) and expanding into SLC NAND, eMMC and MCP product lines.
