As a non-volatile flash memory,NOR Flash chip can not only keep data from being lost after power failure,but also support electric signal erasure,giving consideration to durability and flexibility.Compared with the traditional mechanical hard disk,Yingshang's NOR Flash chip has natural advantages such as strong shock resistance,low power consumption,light weight and so on,and has already become the core storage scheme of U disk,solid state hard disk,smart phone,vehicle-mounted equipment and various Internet of Things terminals.
 

NOR Flash chip adopts parallel addressing structure,is equipped with independent address lines and data lines,has regular hardware interfaces,and supports single-byte random addressing,which means it can realize the function of on-chip execution(XIP).When the device is started,the program code can run directly in NOR Flash without being loaded into the system RAM first,thus obtaining extremely low read delay and faster startup response.This feature makes NOR Flash chip especially suitable for storing boot programs,firmware and key data that need high reliability.
 

The nonvolatile flash NOR Flash chip GT25Q10C-U represented by yingshang integrates many practical features in a compact package:the working voltage range is 1.65~3.6V,which supports wide voltage environment;The highest clock speed reaches 120MHz.With SPI,D-SPI and Q-SPI interface modes,the transmission bandwidth can be flexibly adjusted according to actual needs.The working temperature of NOR Flash chip covers-40℃to 125℃,and it can run stably even in cold or high-temperature industrial environment.Its erasing life is about 100,000 times,data retention time is long,and its heat resistance and low power consumption are outstanding.
 

However,NOR Flash is not without shortcomings.Compared with NAND Flash,NOR Flash chip has lower storage density,higher unit capacity cost and slower writing and erasing speed.However,in the scenes of small capacity,high reliability and quick response,such as industrial control,automotive electronics,smart wear,communication modules,etc.,NOR Flash chips such as GT 25 Q 10 C-U still have irreplaceable competitiveness.It can provide a mature and reliable solution,whether it is used as the main boot memory of equipment or used to store solidified code that needs to be read frequently but rarely changed.
