SPI Flash Memory ICs

SPI NOR flash memory is a non-volatile storage technology that combines NOR flash architecture — which allows random byte-level read access, making it ideal for code execution — with the SPI serial interface for easy integration. It is commonly used for embedded firmware storage, BIOS chips, microcontroller program memory, and automotive control systems where reliable, fast read performance is critical.

SPI (Serial Peripheral Interface) is a communication protocol used for short-distance data transfer between devices. SPI flash refers specifically to flash memory chips that use SPI as their interface bus. In other words, SPI is the communication standard, while SPI flash is a category of non-volatile memory component that communicates using that standard. Many flash ICs also support other interfaces such as parallel bus.

NOR flash allows random access at the byte level, making it suitable for code execution directly from memory (XIP). NAND flash is optimized for high-density sequential data storage, offering lower cost per bit but requiring data to be copied to RAM before execution. NOR is preferred for firmware and boot code, while NAND is used for mass storage applications like SSDs and memory cards.
