Memory Technology

High-Endurance Serial EEPROM and Serial SRAM Memory

Since data storage is a critical factor, a reliable memory such as a serial EEPROM has been the industry preference for many years. Our 24xxx and 25xxx serial EEPROM devices support an I²C and SPI serial interface respectively.

Flash Memory

For applications with higher-density memory requirements, our NOR Flash memory products with patented and proprietary SuperFlash® nonvolatile Flash memory cells are an ideal solution. SuperFlash memory uses a split-gate cell design and a thick-oxide tunneling injector to offer you significant cost and reliability benefits. Superior reliability of 100,000 cycles endurance and greater than 100 years of data retention ensures robust and reliable designs for meter applications. Small sector architecture enables a system to choose the right amount of data/code to be erased to update contents, allowing seamless partition of program and data code to occupy less memory space.

We offer multiple interfaces to satisfy different design needs. Parallel Flash offers asynchronous random access through a dedicated address bus. SQI™ Flash memory reads and writes through a 4-bit multiplexed synchronous serial communication interface to enable  low-pin-count, high-bandwidth code Execute-in-Place (XIP) applications. SPI Flash is a cost-effective option to store the bootloader code, making it available for downloading into shadow memory upon power up.
