| F-RAM products combine the nonvolatile data storage capability of ROM with the benefits of RAM, which include a high number of read and write cycles, high speed read and write cycles, and low power consumption. Our F-RAM product line features various interfaces and densities, which include industry-standard serial and parallel interfaces; industry standard package types; and 4-kilobit, 16-kilobit, 64-kilobit, 256-kilobit, 1-megabit, 2-megabit, and 4-megabit densities. |
|
| 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. |
