　　对新功能的需求正在推动快速汽车信息娱乐增长。九百万汽车信息娱乐系统在201生产，预计年产量将迅速增长到6000万由2019。汽车信息娱乐系统（如图1所示）提供了新的功能，如实时本地交通和零售信息，基于雷达的泊车辅助和安全系统，独立的后方乘客音频/视频，无线互联网和自适应语音控制。这些新功能需要额外的高性能，高可靠性的非易失性存储器。EEPROM不能满足这些要求而不增加设计成本。汽车信息娱乐系统需要高性能、高可靠性、低成本的非易失性存储器。

　　Common design problems engineers face include：

　　Automotive infotainment systems must store settings， status， and navigation data on power loss.

　　The Soak Time for EEPROMs requires 5 ms of active power per Page Write.

　　The Soak Time requires additional capacitors or batteries to perform a Page Write on power loss， increasing system cost.

　　Automotive infotainment systems exceed the 1-million-cycle Write Endurance limitation of EEPROMs.

　　Wear leveling is required to improve EEPROM Write Endurance to support a 20-year automotive lifetime requirement.

　　Wear leveling requires up to 8x the memory capacity and additional software， thus， increasing system cost.

　　Automotive manufacturers require AEC-Q100-qualified non-volatile memories.

　　Cypress‘s F-RAM solves these problems. F-RAM requires no Soak Time， eliminating the need for additional capacitors or batteries to complete a Page Write on power loss. It also provides 100 trillion write cycles， eliminating the need for Wear Leveling. Cypress now offers AEC-Q100-qualified memories in volume. Therefore， Cypress F-RAM is a high-performance， high-reliability， low-cost replacement for EEPROMs in a fast-growing market.
