TDK Launches SD And microSD Memory Cards For Industrial Applications
Today TDK Corporation announced the gradual launch of SD Memory cards (MMRD4 series) and microSD Memory cards (MURD4 series) from January 2018. Both series support UHS-I for industrial application.

The rapid progression of IoT has increased demand for smaller SD/microSD Memory cards with low power consumption for the storage of sensor information. However, as SD/microSD Memory cards for general use adopt TLC and MLC type flash memory to reduce costs, they are largely unsuitable for industrial application in terms of durability and reliability.
The MMRD4 and MURD4 series consist of highly reliable SD/microSD Memory cards equipped with very durable SLC/pSLC flash memory as well as the newly developed SD controller, TDK GBDriverRD4. In addition to data retention capacity and durability, the cards feature robust data security in the event of power interruption, ensuring safe usage in IoT devices that are often turned off to conserve power.
