Ну, наконец-то, появится uC с FRAM на борту вместо EEPROM. "Скорость записи приближается к скорости чтения", практически неограниченное кол-во циклов записи +++ http://ti.com/rfid/govid/imgs/rf360_architecture_final.gif

FRAM – The Next Level of Performance Beyond EEPROM
FRAM enables faster personalization, higher document manufacturing yields, the ability to incorporate future additional biometric data and “write-on-the-fly” capability. It is a key technology for next-generation government ID solutions.
* Fast write speeds – Eliminates the difference between write and read times
* Superior performance – Due to low voltage and ultra low-power operation
* Enhanced data reliability – Superior radiation hardness and inherent tearing protection
* Inexhaustible write endurance – More than 10 million times higher write capability (FRAM has100 trillion write/read cycles)
* Scalable for future needs – Significant reduction in IC manufacturing process steps, smaller cell size and more memory capability
