Inside a Ferroelectric RAM Chip

Ferroelectric memory (FRAM) is a unique storage technique using a special material to store data. It offers rapid write speeds and durability, lasting for decades. Despite these advantages, FRAM is not widely used due to its high cost compared to flash memory. The history of FRAM dates back to the 1950s, with many companies working on it until the 1970s. George Rohrer played a key role in reviving FRAM with Ramtron in 1984. The chip structures and fabrication process of FRAM are complex, contributing to its high cost. Currently, FRAM remains a niche product, mainly used in specialized applications like satellites.
