铁电和普通eeprom不一样吧

铁电不是说可以直接写，不用等待擦除写入的时间，普通eeproom需要等待吧。您看看

Unlike other nonvolatile memory technologies, there is no
effective write delay with F-RAM. Since the read and write
access times of the underlying memory are the same, the user
experiences no delay through the bus. The entire memory cycle
occurs in less time than a single bus clock. Therefore, any
operation including read or write can occur immediately following
a write. Acknowledge polling, a technique used with EEPROMs
to determine if a write is complete is unnecessary and will always
return a ready condition.
