Indefinite retention of recorded data is an ideal choice for MRAM

Time:2021-11-22

MRAM can be used for data recording, Internet of things nodes, machine learning / artificial intelligence in edge computing devices and RFID tags in hospitals.

 

Data recorders require multi megabit nonvolatile memory to accommodate long-term data accumulation. They are usually powered by batteries, but they can also rely on collected energy, so they need low-power memory. In case of power failure, the recorded data must be retained indefinitely.MRAMIs the ideal choice.

 

MRAM persistence, combined with extremely low energy consumption mode, enables the code and data of IOT nodes to operate from energy harvesters or battery sources under minimal shape factors. Startup time is usually an important consideration for IOT nodes. MRAM uses a code in place structure to reduce the required startup time due to DRAM orsramThere is less demand, so the overall bill of materials cost is reduced.

 

The persistence provided by MRAM makes it possible for the machine learning of the new generation of Internet of things nodes. In this node, the reasoning algorithm does not have to be reloaded every time after the device wakes up. Local processing such as analyzing sensor data and making decisions can reconfigure nodes in some cases. This local intelligence requires persistent low-power memory. These devices can realize local rough reasoning in real time, and can use cloud for enhanced analysis.

 

The high speed of MRAM is conducive to machine learning on edge devices such as enterprise resource planning (ERP) system, manufacturing execution system (MES) and supervisory control and data acquisition (SCADA) system. In these systems, data is analyzed, intermediate patterns are identified and shared with adjacent domains. Edge architecture requires processing speed and persistent memory.

 

Designers can alsoMRAMIt is used in medical and health care equipment, in which radio frequency identification (RFID) is the most typical. Its low power consumption, coupled with its immunity to radiation, makes it very suitable for the medical environment. RFID tags are widely used in hospitals, including inventory management, patient care and safety, identification of medical equipment and identification and monitoring of consumables.
