FeRAM memories constitute themselves as a robust counterpart to the mainstream NVRAM memories. Their unique properties, such as radiation resilience and low voltage operation, together with high speed writing and reading, high and long lasting remanence and very good endurance to cycling endorse them in the data storage domain. However price, poor scalability, the destructive way of reading and the necessary consequent re-writing represent technical drawbacks that diminish their practical value. This paper presents a new paradigm of completing previous efforts towards fast nondestructive reading of FeRAMs. An intermittent low intensity IR (infrared) laser diode generates a pyroelectric signal in the ferroelectric material. The amplitude and phase of this response depends on the state of polarisation of the ferroelectric. Comparing the phase of the electric response with the phase of the illuminating radiation (on/off), a decisive indication of the poling sense in the ferroelectric is given. Aiming to circumvent the notorious slowness of the pyroelectric response the array is continuously illuminated with the pulsating laser, which ensures a prompt answer from every bit of memory. The reading speed is, practically, limited by the electronics.

FeRAM存储器可作为主流NVRAM存储器的强大替代品。它们具有独特的特性，例如辐射弹性和低电压操作，以及高速的读写功能，持久的高持久性以及在数据存储领域中非常出色的耐循环性。但是，价格，可伸缩性差，破坏性的读取方式以及随之而来的必要重写，都代表了降低其实用价值的技术缺陷。本文提出了一种新的范例，可以完成以前对FeRAM的快速无损读取的努力。间歇性的低强度IR（红外）激光二极管在铁电材料中产生热电信号。该响应的幅度和相位取决于铁电体的极化状态。将电响应的相位与照明辐射的相位（开/关）进行比较，可以确定性地指示铁电体中的极化方向。为了避免热释电反应缓慢的问题，用脉动激光连续照射阵列，以确保从存储器的每一位得到迅速的答复。读取速度实际上受电子设备的限制。
