Processor Companions: Single chip solutions that replace discrete components to reduce cost and board space.

Ramtron’s Processor Companion is a complete support and peripheral solution with highly integrated mixed signal and analog functions for processor-based systems. Never before has a solution combined the fast read/write performance and unlimited endurance of nonvolatile FRAM (ferroelectric random access memory) with a real-time clock (RTC), processor supervisor, and other common peripherals.

FRAM offers a unique set of features relative to other semiconductor technologies. Traditional mainstream semiconductor memories can be divided into two primary categories -- volatile and nonvolatile. Volatile memories include SRAM (static random access memory) and DRAM (dynamic random access memory). SRAMs and DRAMs lose their contents after power is removed from the electronic system. RAM type devices are very easy to use, and are high performing, but they share the annoying quirk of losing their mind when the lights go out.

Nonvolatile memories do not lose their contents when power is removed. However all of the mainstream nonvolatile memories share a common ancestry that derives from ROM (read only memory) technology. As you might guess, something called read only memory is not easy to write, in fact it's impossible. All of its descendants make it very difficult to write new information into them. They include technologies called EPROM (almost obsolete now), EEPROM, and Flash. ROM based technologies are very slow to write, wear out after being written a small number of times, and use a large amount of power to write.

FRAM offers features consistent with a RAM technology, but is nonvolatile like a ROM technology. FRAM bridges the gap between the two categories and creates something completely new -- a nonvolatile RAM.
