Portable ultrasonic scanner is widely used in medical diagnosis,industrial detection and other fields because of its non-invasive and real-time imaging characteristics.This kind of equipment helps the operator to make quick judgment and analysis by receiving the sound waves reflected by objects and converting them into visible images.In order to ensure the stability and reliability of the equipment,its storage system must meet two key requirements:first,it can safely store configuration information and image report data,and second,it can ensure that data is not lost in case of unexpected power failure.MRAM(Magnetoresistive Random Access Memory)is an ideal storage solution to meet these stringent requirements,which can be used as both configuration memory and image and report memory,providing solid data guarantee for portable ultrasonic equipment.
 

Compared with traditional SRAM,nvSRAM and other storage schemes,MRAM has outstanding performance in reliability,energy efficiency and system simplification.Its main advantages include:

No need for spare batteries or capacitors:Unlike SRAM,MRAM does not need additional voltage controllers,batteries and battery sockets;Compared with nvSRAM,it also saves external capacitors,simplifies circuit design and improves system reliability.

Zero risk of power failure data:Even in the case of sudden power failure,MRAM can ensure the safe storage of data,and the recovery time is extremely short,so it is suitable for medical and industrial scenes that require high data integrity.

Long-term data preservation:MRAM can still preserve data for more than 10 years in high temperature environment,which is suitable for long-term deployment of equipment.

Almost unlimited reading and writing endurance:support up to 10 14 writing operations,unlimited reading times,far beyond the traditional Flash memory,suitable for frequent data update applications.

Built-in security mechanism:MRAM has data security function,which enhances the system information security protection.
 

Key parameters of MRAM chip:

To meet the design requirements of different portable ultrasonic devices,MRAM provides a variety of capacity and power supply options,and is compatible with mainstream interface standards:

Storage capacity:1Mb,2Mb,4Mb,8Mb,16Mb,32Mb,64Mb.

Operating voltage:1.8V(range 1.71V-1.98V)or 3.3V(range 2.7V-3.6V).

Interface type:supports single-wire,double-wire and four-wire SPI,and is compatible with SDR and DDR modes.

Data retention period:the data can still be kept for more than 20 years in the high temperature environment of 85℃

Write times:MRAM can reach 10 14 times,with unlimited reading.

Error correction support:MRAM does not need external ECC circuit,which reduces the design complexity.

Packaging form:8WSON,8SOP,16SOP,24FBGA and other industrial standard packages.
 

In high reliability equipment such as portable ultrasonic scanner,the selection of memory directly affects the stability and data security of the whole system.MRAM has become an ideal memory chip for such applications because of its non-volatility,high durability,low power consumption and high integration.It not only simplifies the hardware design,improves the endurance and reliability of equipment,but also provides strong support for data integrity and long-term operation of equipment in medical and industrial fields.
