Systematic evaluation of ferroelectric memory (FRAM) data retention mechanisms under high temperature exposure are reported. The FRAM devices are embedded on ultra-low power, analog-enhanced 130nm and 180nm CMOS technologies. Capability of the FRAM to retain data through 260°C Pb-free solder assembly reflow is demonstrated. The 130nm FRAM is shown to achieve the equivalent of 10 years data retention at 125°C, with intrinsic margin comparable to the 180nm FRAM, previously shown to achieve 10 years at 125°C retention.
