two groups.
random access memory like (1). The FRAM market has expanded over the last few years with
applications that require security and authentication as in ID cards, and as a replacement for
EEPROM. Given the way in which information has become so easily accessible on the Internet,
it is not an overstatement to claim that FRAM has become an indispensable device for realizing
security and authentication functions.

Do you know what FRAM is?
(1) memory that loses its contents when power is lost (volatile)
(2) memory that retains its contents even when power is lost (non-volatile)
FRAM (Ferroelectric Random Access Memory) is non-volatile like (2) and can be used as
Although many types of memory devices are available today, they are largely separated into
: SRAM, SDRAM, etc.
: EEPROM, FLASH memory
