The library allows efficient reading from and writing to [Fujitsu FRAM](http://www.fujitsu.com/global/products/devices/semiconductor/memory/fram/overview/features/index.html) memories using I2C and allowing use of objects such as arrays or structures in addition to writing single bytes at a time. The FRAM memory has several advantages over conventional SRAM in that it allows at least 10 trillion read/write cycles which means that the programmer doesn't have to worry about heavy use of FRAM for changing data. The FRAM is 5V tolerant and there is an [Adafruit breakout](https://www.adafruit.com/product/1895) available. +Up to 8 devices can be put on an I2C and the library allows several memories to be treated as one large contiguous memory. The following memories are supported: + + + + + + + + + + + + + + + + + + + + + + +
