Abstract

A ferroelectric destructive read-out memory system includes a power source, a memory array including a memory cell, and a logic circuit for applying a signal to the memory array. Whenever a low power condition is detected in said power source, a disturb prevent circuit prevents unintended voltages due to the low power condition from disturbing the memory cell. The disturb prevent circuit also stops the operation of the logic circuit for a time sufficient to permit a rewrite cycle to be completed, thereby preventing loss of the data being rewritten.
