It is short for Ferroelectric RAM, which is a key in of RAM.
you could know its definition, history, as well as pros and cons.
FRAM is one of the alternativenon-volatile random-access memorytechnologies that provide the same functions asflash memory.
The data retention time of FRAM at +85C exceeds 10 years (up to decades at lower temperatures).
Like DRAM, FeRAMs read process is destructive, so it requires a write-after-read architecture.
History
Usage
FRAM occupies only a small part of the entire semiconductor market.
Compared with alternative NVRAM, flash memory sales are much larger to support greater R&D efforts.
Other emerging NVRAMs, such asMRAM, may attempt to compete with FeRAM to enter a similar niche market.
Flash usually requires nine masks.
For example, this can integrate FeRAM into a microcontroller, and the simplified process can reduce costs.
However, the materials used to manufacture FeRAM are not commonly used in CMOS integrated circuit manufacturing.
