FRAM occupies the medical field and the smart meter industry

Fujitsu Semiconductor has attracted industry attention for its solutions and applications in the medical field and smart meters. FRAM has received much attention in these two areas, which is inseparable from its huge advantages in the medical field and the smart meter industry.

The production process of medical equipment and the reliability of the device directly affect the patient's life safety. There is no mistake in the medical field. The medical field places high demands on the high reliability of devices. Compared with traditional memory devices, Fujitsu Semiconductor's FRAM has the following advantages. It is these huge advantages that make the Fujitsu Semiconductor FRAM unscrupulous.

First, compared to traditional non-volatile memories, FRAM consumes much less power and writes faster. For similar writes, FRAM consumes only 1/100th of EEPROM. The write time of FRAM is 1/40000 of EEPROM, reaching the level of traditional volatile memory such as SRAM and DRAM. Moreover, FRAM's read/write endurance is far superior to EEPROM and Flash memory. EEPROM and Flash memory can be written about 1 million times (106 times), FRAM can be written at least 1013 times, or the number of writes can reach more than 10 million times of the first two memories.

Second, ferroelectric memories that use polarization techniques to preserve data do not suffer from data loss when exposed to radiation. In the case of EEPROM and Flash memory, saving data depends on whether charge is present in the memory area of ​​the device, and radiation can cause charge drift, causing data to be corrupted.

Finally, there is no need for a backup battery and instant power-off protection. This feature is especially suitable for the use of portable medical devices, while reducing the cost of equipment maintenance.

In summary, Fujitsu Semiconductor FRAM features: non-volatile, low power, high-speed programming, high read and write durability, anti-interference ability, radiation resistance and no need for backup batteries. This is the main reason why Fujitsu Semiconductor FRAM can occupy high-end medical equipment. These unmatched advantages add new practical value to medical devices and systems. Fujitsu Semiconductor FRAM has long been used in CT scanners and other large devices, and its use in smaller medical devices is increasing. In order to achieve certification for the production control of medical devices and biopharmaceuticals, RFID with FRAM has also become more and more popular.

In many countries, FRAM has been widely used in smart meters, and its excellent features such as fast writing, almost unlimited read/write, low power consumption and tamper resistance will promote the future development of smart meters.

China National Network plans to install 240 million smart meters nationwide in 2011-2015, but by the end of 2012, China had installed 184 million smart meters. In 2013, the number of tenders for the first two smart meters reached 41,495,500. In the next two years, the number of tenders for smart meters is expected to remain between 70 million and 80 million units per year.

The rapid development of smart meters has made consumers pay more and more attention to the accuracy of meter data. FRAM uses the ferroelectric effect of ferroelectric crystals to achieve data storage. It is characterized by fast speed, the ability to operate like RAM, very low read and write power consumption, and no problem with the maximum number of writes such as E2PROM. These advantages make FRAM increasingly used by applications that require high reliability.

In the smart meter, Fujitsu Semiconductor FRAM has completed the task that traditional memory can't accomplish, which brings great convenience to the design of smart meter.

1. Record data in real time. The measurement unit in the grid smart meter can use the data log system to record energy consumption and related changes in real time. With such a system, data is required to be written at a frequency of approximately twice per second. The data log system of the communication unit stores the data for monitoring the working state and control data of the power grid to ensure optimal distribution of power. The ideal method is to record these data frequently, and the fast write and frequently read/write characteristics of Fujitsu Semiconductor FRAM become critical.

2. Reduce power consumption. Fujitsu Semiconductor FRAM helps reduce the total power consumption of smart meters. With smart meters, you need to monitor the battery's working process to ensure that the meter is always in operation in the event of a power outage or unpredictable situation where there is no power supply, which is why the meter's power consumption is small. . FRAM's power consumption is very low, and it can save data in the event of a power outage, which is very useful in reducing the power consumption of the meter. And the low power consumption of FRAM helps to extend battery life.

3. Improve data security. The smart meter memory stores data on household electricity usage. To ensure the security of private information, the meter requires higher data security. Fujitsu Semiconductor's FRAM has tamper-proof features that make the data security of the meter much stronger than systems that use traditional memory. When developing smart meters with Fujitsu Semiconductor FRAM, it is very important to ensure safety and ensure data reliability.

Fujitsu Semiconductor FRAM can occupy the medical field and the smart meter industry due to its own advantages. I believe that the application field of Fujitsu Semiconductor FRAM is not limited to this. At present, Fujitsu Semiconductor FRAM is also used in industries such as measuring instruments (three-phase electric meters and water meters, gas meters, etc.), power automation, medical equipment and medical electronic labels, automobile after-loading equipment, POS machines/financial ATM machines, and the like. The outlook for the 2015 Fujitsu Semiconductor FRAM market will be even brighter.
