[News] Cmsemicon Makes a Foray into NOR Flash Market, New Product Coming

China-based Cmsemicon launches its first non-volatile memory chip. It unveils its first Flash product, CMS25Q40A, which marks the company’s formal and substantive entry into the memory semiconductor sector.

It’ s reported that the product is a 4M bit low-power SPI NOR Flash device. It features a memory array comprising 2,048 programmable pages, with a page size of 256 bytes. The maximum programmable data size per write operation reaches 256 bytes. The chip supports multiple erase modes and offers advantages such as low cost, low power consumption, high-speed SPI read/write performance, and data retention without power. It is designed to meet small-capacity storage requirements, including embedded MCU program storage, configuration storage for compact smart hardware, low-power IoT terminal storage, and companion storage for peripherals or modules.

Founded in 2001, Cmsemicon is an integrated circuit (IC) design company with a core focus on microcontroller unit (MCU) R&D and design. The company is dedicated to chip design and sales, providing high-performance, low-power, and highly integrated chip products and system solutions for a wide range of intelligent terminal applications, including consumer electronics, smart home appliances, industrial control, and automotive electronics.

The memory chip market comprises several segments, including DRAM, NAND Flash, NOR Flash, and EEPROM. Among them, DRAM and NAND Flash account for the majority of the overall market. By comparison, the NOR Flash segment is relatively smaller in scale but increasingly competitive, with major Chinese domestic players such as GigaDevice and Puya Semi.
