In the fields of industrial control,intelligent equipment and aerospace electronics,memory chips should not only ensure high-speed reading and writing,but also not lose data after power failure.MRAM(Magnetoresistive Random Access Memory)is just such a nonvolatile memory with both SRAM speed and DRAM capacity.As the MRAM product promoted by NETSOL,S3A4004V0M is gradually becoming a popular choice to replace the traditional storage scheme.
1.introduction of NETSOL first-class proxy MRAM memory chip S3A4004V0M.
As the key model of NETSOL's first-class agent,the MRAM memory chip S3A4004V0M supports the working voltage of 2.70V~3.60V,and the frequency can be selected from 108MHz or 54MHz,providing two wide temperature options from-40℃to 85℃and-40℃to 105℃,which is suitable for harsh environment.MRAM memory chips are packaged in industrial standard formats(8WSON,8SOP,16SOP,24FBGA),and are compatible with single,double and four-wire SPI interfaces(both SDR and DDR modes are supported).
2.Advantages of NETSOL first-class proxy MRAM memory chip S3A4004V0M.
Unlike traditional charge storage-based DRAM or Flash,MRAM works by using giant magnetoresistance(GMR)and tunneling magnetoresistance(TMR)effects generated by electron spin.MRAM memory chip records"0"and"1"by changing the magnetization direction of the free layer in the magnetic structure.The reading and writing speed can reach 10ns level,which is equivalent to SRAM.At the same time,it has non-volatile characteristics-the data remains intact after power failure.The write life of MRAM memory chip is more than 10 15 times,which is almost infinite,far better than Flash and FeRAM.In addition,MRAM has very low power consumption and can be integrated with standard CMOS process,which is beneficial to reduce manufacturing costs.
3.Application scenario of NETSOL first-level proxy MRAM memory chip.
In the actual scene,this MRAM chip is very suitable for code storage,data recording,backup and working memory of industrial equipment.It can directly replace Flash,FeRAM,nvSRAM and so on,without modifying the circuit design.In addition,because MRAM is naturally radiation-resistant,it also plays an important role in space science and technology,medical equipment and other fields that require strict reliability.The low power consumption and nonvolatile characteristics of MRAM memory chips are also suitable for environmental protection front-end devices such as mobile computers,home servers and digital cameras.
