In recent years, the Wall Street Journal recently an article pointed out that in recent years, smart phones, PC, Tablet PC and other equipment evolution is not so fast in the past, but they are a new way to promote innovation, hardware manufacturers more specific tasks for customization chip. Yes, the diversity of technology is bringing more optimized design options like "customization" for a variety of applications. The same is true of the embedded system data storage area, where different storage technologies are offering "customized" solutions for many applications, Fujitsu is doing this in FRAM, NRAM, and ReRAM technology.
"Storage performance is critical as a key component of the system," said Feng Yixin, director of product management at Fujitsu Electronic Components (Shanghai) Co., Ltd., in a recent public speech that "the read and write speeds of various systems to read and write Write power, read and write power consumption, security and power requirements are different, storage technology is to break down. "The company is almost unlimited number of read and write, ultra-low power and ultra-high read and write speed FRAM memory in recent years in a variety of markets is widely used is a good example, including medical electronics, measuring instruments, industrial automation, automotive electronics, and so the market has been very common. "By 2019, Fujitsu will offer embedded solutions for embedded systems including FRAM, NRAM and ReRAM, which have unique advantages."
As a "atypical" of storage technology, FRAM technology itself has a very strong atypical characteristics - it is the use of ferroelectric materials (PZT, etc.) ferroelectric and ferroelectric effects for non-volatile data storage memory, Can be done like SRAM random read, but also with Flash and EEPROM, like power-down after the important data in real time to save the characteristics. In addition, Fujitsu Semiconductor FRAM with high-speed write performance, to ensure that 10 trillion times the number of read and write, the most suitable for real-time recording data measurement instrument applications and other electronic parts.
"Even if the power supply system is out of power or dropping, the data in the write operation can be completely protected. Related measuring instruments related to basic life such as electricity meters, as well as industrial automation equipment, financial terminals, etc. requiring high reliability Application, so our FRAM has been very widely recognized and used. "Feng Yixin pointed out. In fact, this personalized "customized" product solution has been extended to more applications, Fujitsu recently launched a new FRAM solution - MB85RS128TY and MB85RS256T for the first time the working environment temperature extended to up to 125 degrees Celsius, specifically for the car industry and the installation of motor control of industrial machinery and other design, and in line with the harsh automotive industry AEC Q100 standard specifications.
Fujitsu last year the industry's highest density ReRAM (variable resistive memory) product MB85AS4MT, with the industry's lowest non-volatile memory read power (5MHz frequency average consumption of only 0.2mA). ReRAM will DRAM read and write speed and SSD non-volatile integration in one. In other words, the memory can still remember the data after turning off the power. "If ReRAM has enough space, a PC with ReRAM will not need to be loaded." Feng Yixin's example is impressive about the fast write feature of ReRAM. "ReRAM has always been considered an alternative to future flash memory. Storing 1T of data on a single chip, which is 20 times faster than the flash memory.
Fujitsu Semiconductor has become the world's first manufacturer to announce mass production NRAM, NRAM performance is DRAM 1000 times, but like NAND flash memory as the new memory data storage. Fujitsu Semiconductor plans to develop a custom embedded memory-level memory module with DDR4 interface by the end of 2018. NRAM products will be targeted at data centers and servers, and may be used for consumer products, even to mobile devices. Due to the low energy consumption of NRAM, it does not require background data erase operation, it may extend the mobile device's standby time to several months.
High read / write durability and high-speed FRAM has become similar to the power meter industry applications such as storage of important data of the best program; and low-power and high-capacity ReRAM are those to read the main operation, replace the battery difficulties, Difficult to keep data for a long time to maintain the best solution for the flow meter; high read / write durability and high capacity NRAM will also be another important component to improve the performance of the meter. "FRAM is still the current star" Huadan "of Fujitsu storage solutions, and ReRAM and NRAM will be the storage system for embedded systems." As a product that has been massively delivered to the market for more than 18 years, FRAM is still the current star " The package offers a perfect complement.
