| Ramtron integrated products combine the all the benefits of F-RAM memory technology with carefully selected mixed-signal (analog and digital) functions to create truly unique semiconductor solutions. |
|
| Processor Companions, which include industry-standard serial interfaces, are available in 4-kilobit to 256-kilobit densities along with on-chip integrated mixed-signal functions for processor-based systems. Never before has a solution combined the fast read/write performance and unlimited endurance of nonvolatile F-RAM (ferroelectric random access memory) with a real-time clock (RTC), processor supervisor, and other common peripherals. |
|
| All Ramtron F-RAM products have three distinct properties that make it superior to other nonvolatile memory technologies: |
|
 |
|
Fast write speed |
| F-RAM performs read and write operations at the same speed. Because F-RAM writes data at bus speed, there are no delays before the written data becomes nonvolatile. Floating gate memories have long write delays of 5 milliseconds. F-RAM writes in nanoseconds, essential in applications like auto safety systems. |
|
|
 |
|
High endurance |
| F-RAM offers virtually unlimited write endurance, which means it doesn’t wear out like other nonvolatile memory devices. Floating gate devices experience a hard failure and stop writing in as little as 1E5 cycles, making them unsuitable for high-endurance applications. |
|
|
 |
|
Low power consumption |
| F-RAM operates without a charge pump, enabling low power consumption. Floating gate devices demand high voltage during write operations. F-RAM writes at the native voltage of the manufacturing process: 5V, 3V, or even less on more advanced processes. |
