Abstract:

The F-RAM is required to record important data in experiments under complex conditions.The power down protection function is necessary to prevent the already valid data from being covered on secondary electricity.A design of a power down protection is introduced and realized on FPGA.The design works well on board,and realizes the expected function in related project applications.

Key words: ferroelectric nonvolatile ram;power down protection;field programmable gate array
