

POWER ON/OFF SEQUENCE

If the device does not operate within the specified conditions of read cycle, write cycle or power on/off

sequence, memory data can not be guaranteed.



FeRAM CHARACTERISTICS

*1 : Total number of reading and writing defines the minimum value of endurance, as an FeRAM memory

operates with destructive readout mechanism.

*2 : Minimum values define retention time of the first reading/writing data right after shipment, and these values

are calculated by qualification results.
