Fast response circuits and methods for FRAM power loss protection |
摘要 |
A circuit to protect data on an FRAM during a read operation includes an FRAM voltage regulator having an output to supply an FRAM operating voltage to the FRAM. A voltage monitor monitors a supply voltage for the FRAM to generate a voltage fault signal if the supply voltage falls below a predetermined value. And a circuit responsive to the voltage fault signal maintains the FRAM operating voltage above a voltage required to assure data integrity of the FRAM for a sufficient time required to perform an FRAM read operation. |
