Memory: FM25V20-GTR Application Field and Working Principle

The FM25V20-GTR is a type of non-volatile memory (NVM) of the ferroelectric random-access memory (FRAM) family. This type has a variety of suitable applications, as it provides a non-volatile solution with high speed, low power consumption, reliable operation and low cost. Additionally, it is radiation hardened and offers high level protection against shocks, vibrations, and extreme temperatures.

Application Field

The FM25V20-GTR is well-suited for use in military and avionics systems because of its rigorous protection against harsh environmental conditions. As such, it is commonly used in high-end industrial equipment and aerospace products, as well as medical instrumentation in medical, diagnostic and healthcare sectors. In addition to industrial and aerospace applications, where this type of memory can be used for navigation and navigation systems as well as for storing security sensitive data.

In automotive industry, FM25V20-GTR is also widely used. At its shipping time, it was already adopted by some new control scheme for the components used in the car body, such as brakes and steering system. Nowadays, FM25V20-GTR is commonly used in the application such as Hybrid Vehicle Control Unit, Telematics gateway, ECU (Electronic Control Unit), and Instrument cluster.

Working Principle of FM25V20-GTR

The FM25V20-GTR is composed by a two dimensional array of ferroelectric memory cells. It is electro-statically programmed and erased by using the cell programming voltage and gate potential. All the procedure is done synchronously under one pulse of clock wave. The working principle of nonvolatile FM25V20-GTR FRAMs is actually two dimensional addressing: binary bits and a 3-state analog voltage, which is the ferroelectric hysteresis of the memory cell. Discharge and charge time of that voltage string depend on the conditions of the peripheral circuit. The integrated circuits are organized in blocks with each block consists of 64 words of 16-bits per cell.

Since FM25V20-GTR use ferroelectric layer instead of floating gate, its reliability and endurance are much higher than the flash memory. Meanwhile, its bit decay can be reduced by writing with a voltage smaller than 3V. Thus, FM25V20-GTR have become one of the most reliable nonvolatile memories available nowadays.

Advantages of FM25V20-GTR

Unlike other types of non-volatile memories, one of the major advantages of FM25V20-GTR is its low power consumption. It is typically rated at 1/10th the power consumption of flash memories and requires only 0.5V and 1.8V for read and write operation, respectively. This type of memory also offers fast access time, being able to carry out data transfers in 25ns or less. Additionally, it has fast speed of writing and erasing, as well as radiation and temperature resistance. Due to its low power consumption and high speed performance, this type of memory is well-suited for applications where power-saving is an important factor and is becoming increasingly popular in the industry.

Conclusion

The FM25V20-GTR is an advanced type of non-volatile memory, which has a wide range of applications due to its low power consumption, reliable operation, high speed performance, and resistance against temperature and radiation. As such, it is a great choice for use in industrial, aerospace, automotive and medical applications. Furthermore, the fast access and write/erase time make it one of the most attractive nonvolatile memories available in the market.
