EEE endurance caculating equation

yaojianhang — Wed, 12 Jul 2023 12:27:11 GMT

HI,

In AN4306 and AN4282, the RM provides EEE endurance caculating equation like below, I wonder what the "(2 X EEESIZE)" means?

I already know that beacause of eee's round robin write mechanism, "EFlash/EEESIZE * RecordEfficiency" means that writing all eee locations in so much times that EFLASH is fully erased once.

BR,
