The TS-7120 has 16Kbit ferroelectric random access memory (FRAM) organized as 2KB. It is accessible via the SPI bus.

The FRAM may be accessed from userspace. It will appear as an EEPROM at (typically): /sys/class/spi_master/spi32766/spi32766.0/eeprom

Note that the exact filename under /sys/class/spi_master/ might be different from the above.

The datasheet is available from Cypress Semiconductors' website.
