# ferroelectric random-access memory > electronic device using the ferroelectric effect to produce low density random access memory **Wikidata**: [Q703656](https://www.wikidata.org/wiki/Q703656) **Wikipedia**: [English](https://en.wikipedia.org/wiki/Ferroelectric_RAM) **Source**: https://4ort.xyz/entity/ferroelectric-random-access-memory ## Summary Ferroelectric random-access memory (FeRAM) is an electronic device that utilizes the ferroelectric effect to create low-density random access memory. As a type of non-volatile random-access memory, FeRAM retains its stored information even when power is turned off, distinguishing it from volatile memory types like dynamic random-access memory (DRAM) and static random-access memory (SRAM). ## Key Facts * Ferroelectric random-access memory is a subclass of non-volatile random-access memory. * It is an electronic device that employs the ferroelectric effect. * FeRAM produces low-density random access memory. * It retains its information when power is turned off, unlike DRAM and SRAM. * Common aliases include FeRAM, F-RAM, FRAM, and ferroelectric RAM. * An image of FeRAM by RAMTRON is available at https://commons.wikimedia.org/wiki/Special:FilePath/Medical_Econet_PalmCare_-_CPU_module_-_Ramtron_FM18L08-70-SG-5631.jpg. * It is also classified as a Ferroelectric Floating Gate Random Access Memory. * The entity has 19 sitelinks across various platforms. ## FAQs ### Q: What is ferroelectric random-access memory (FeRAM)? A: Ferroelectric random-access memory (FeRAM) is an electronic device that uses the ferroelectric effect to create random access memory with low density. It is notable for being non-volatile, meaning it retains its data even when power is removed. ### Q: How does FeRAM differ from other types of RAM like DRAM and SRAM? A: The primary difference is its non-volatile nature. Unlike dynamic random-access memory (DRAM) and static random-access memory (SRAM), which lose their data when power is turned off, FeRAM maintains its information without continuous power. ### Q: What is ferroelectric random-access memory also known as? A: Ferroelectric random-access memory is commonly known by several aliases, including FeRAM, F-RAM, and FRAM. It is also referred to as ferroelectric RAM. ## Why It Matters Ferroelectric random-access memory (FeRAM) is significant because it addresses a fundamental challenge in computing: the volatility of traditional random-access memory. Unlike widely used memory types such as DRAM and SRAM, which require constant power to maintain their data, FeRAM is a non-volatile form of RAM. This means that FeRAM retains its stored information even after the power supply is removed, offering persistent data storage capabilities in a RAM format. This characteristic is crucial for applications where data integrity must be preserved through power cycles or unexpected power loss, without the need for battery backup or slower non-volatile storage mechanisms. By leveraging the ferroelectric effect, FeRAM provides a unique combination of random access speed and non-volatility, enabling the development of electronic devices that can boot faster, consume less power, and offer greater data reliability in specific, often low-density, memory applications. Its ability to retain data without power fundamentally changes how certain types of memory can be utilized in electronic systems. ## Notable For * Being a type of non-volatile random-access memory that retains data when power is off. * Utilizing the ferroelectric effect for data storage. * Producing low-density random access memory. * Its distinction from volatile memory types like DRAM and SRAM, which require continuous power to maintain data. * Its common aliases, including FeRAM, F-RAM, and FRAM. ## Body ### Definition and Classification Ferroelectric random-access memory (FeRAM) is defined as an electronic device that employs the ferroelectric effect to produce random access memory. It is specifically characterized as a low-density form of random access memory. FeRAM is classified as a type of non-volatile random-access memory.
