TDK uses proprietary microcontroller in flash storage disks
Five series of flash storage products from TDK use GBDriver GS2, its proprietary NAND flash memory control IC, which supports serial ATA. They are optimised for industrial, medical, smart grid, transportation and security applications.
As 3D flash memory technology advances, flash storage solutions with capacities over 1 Tbyte are widely used, but data reliability requirements continue to become more sophisticated, explains TDK. With flash storage integrated into edge devices in industrial equipment, and other industrial IoT devices mostly used to store OS or device applications, the demand has increased for highly reliable storage devices that also protect user data.
In addition to auto refresh and data recovery features, the GBDriver GS2 features new error code correction (ECC), the LDPC memory and strong RAID features, and enhances data reliability, says TDK. The five families provide a wide range of storage capacities, from 16Gbyte to 1.6Tbyte.
A standard feature of all five storage products is the internal power back-up protection circuits, with 2D MLC NAND flash memory. There is also write protection with unified write filter (UWF) for Windows 10. Power interruption tolerance is also enhanced with 3D TLC NAND flash memory.
They also offer strengthened security features, including a new firmware anti-tampering feature. TDK’s original anti-spoofing security feature, AES128/256-bit encryption, and ATA security, protects users against falsification and the leakage of data stored in NAND flash memory.
They storage disks can be used in a variety of industrial IoT applications, including in devices such as information terminals and edge computing systems. They are also suitable for industrial computers, factory automation equipment, railway and transportation service equipment. Other uses are in ticket vending machines and banking terminals, medical and data analysis equipment, smart grid equipment and security equipment, for example in security terminals.
TDK Corporation was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products. TDK’s portfolio features passive components such as ceramic, aluminum electrolytic and film capacitors, as well as magnetics, high-frequency, and piezo and protection devices. The product spectrum also includes sensors and sensor systems such as temperature and pressure, magnetic, and MEMS sensors. In addition, TDK provides power supplies and energy devices and magnetic heads.
The products are marketed under the product brands TDK, Epcos, InvenSense, Micronas, Tronics and TDK-Lambda.
TDK focuses on demanding markets in automotive, industrial and consumer electronics, and information and communication technology. The company has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America.
