Ramtron Granted Fundamental Ferroelectric RAM Patent
Ramtron announced today the issuance of U.S. Patent No. 7,672,151 entitled Method for Reading Non-volatile Ferroelectric Capacitor Memory Cell. The patent materially expands Ramtron’s intellectual property portfolio.“W
The new patent covers methods of reading and restoring a 1T/1C F-RAM memory cell. The patent claims fundamental technology for the basic reading and restoring of a 1T/1C F-RAM memory cell including a word line, bit line, a drive line, an access transistor and a ferroelectric capacitor having two different polarization states.
About Ramtron’s F-RAM
Ramtron pioneered the integration of ferroelectric materials into semiconductor products, which enabled the development of a new class of nonvolatile memory, called ferroelectric random access memory, or F-RAM. Ramtron’s ferroelectric memories combine the high speed of DRAM (Dynamic Random Access Memory) with nonvolatile data storage, or the ability to save data without power. Since commercializing the technology, Ramtron has sold more than 300-million F-RAM devices into demanding applications such as automotive safety and entertainment systems, portable medical devices, industrial process control systems, smart electricity meters, and consumer printer cartridges. As the most power-efficient of any nonvolatile memory technology on the market, F-RAM products promise to pave the way for the development of ultra-efficient battery powered products and energy harvesting applications among others.
