Faraday has collaborated with Infineon to develop a SONOS eFlash platform on UMC’s 40nm uLP process. This platform encompasses eFlash subsystem IP, including controller, timing, and cache functions, with a complete eFlash testing solution. The subsystem IP can facilitate the utilization of flash memory technology and accelerate customer’s product development with easy-to-integrate and fast data access features. It, moreover, simplifies SONOS eFlash testing with a built-in self-test (BIST) function to provide customers solid quality advantages. The total solution is designed to meet the demands of AI, smart grid, IoT, and MCU applications.
