FRAM 2 click carries the CY15B104Q 4-Mbit (512K x 8) from Cypress. A ferroelectric random-access memory or F-RAM is non-volatile and performs reads and writes similar to a RAM.
Ferroelectric RAM, better known as FRAM is a random-access memory. It’s famous for fast access times and low power consumption. You can use it in all sorts of applications, especially the ones that require low-power consumption.
The CY15B104Q has high endurance – is capable of supporting 10^14 read/write cycles.
But what does non-volatile mean?
To be volatile is to be unstable. So, non-volatile memory is stable and saves all the data even when the power is off. Or to be more precise this type of memory does not need a continuous power supply to retain data.
