Perhaps the oldest nonvolatile semiconductor memory type is the ferroelectric memory, which recently celebrated its 68th birthday. FRAM predates flash memory, EEPROM, and even UV-erasable EPROM. It’s even older than mask ROM, which wasn’t invented until 1967!
As a matter of introduction to the technology, FRAM, or ferroelectric memory, is a read/write nonvolatile memory technology that performs significantly better than Continue reading “FRAM Turns 68”
