Documentation
FRAM (Ferroelectric Random Access Memory) is a "non-volatile" "random access" memory, which uses ferroelectric film
as a capacitor for storing data.
(Fujitsu utilizes PZT as ferroelectric material)
Combining the advantages of both ROM and RAM devices, FRAM can achieve high-speed read/write and also retain data even after
the power is turned off.
Following are the advantages of FRAM:
♦High-speed writing (1/30,000 of E2PROM)
♦High endurance (1E10 times)
♦Low power consumption (1/400 of E2PROM)
♦Non-volatility
♦Excellent tamper prevention
