Hi  Sir,

之前一直使用小容量的铁电,4Kb/i2c , 目前产品已经稳定量产,但是每年会出现几例读写数据出现问题。现在有一个新的项目,需要选型4Mbit/8Mbit 大容量SPI  Fram,  但是对大容量的稳定性有所担心,是否会出现数据丢失的问题?可靠性不太好?随着FRAM容量的增大,是不是稳定性就越不好?若出现稳定性不好的情况,应该如何解决呢?thanks。

Hi,

There should be no issues with reliability or stability that you should observe with higher density FRAM. In fact the density has got no relation with stability. If you have observed some errors generally we have seen that the causes are related to timing parameter violations or maybe due to some schematic mismatch. You should not observe any data loss problems. 

Thanks,

Pradipta.
