“They meet AEC-Q100/104 Grade 2 standards, supporting case temperature up to 115°C,” according to the company. “The UFS 4.1 devices are designed to fit the needs of infotainment, ADAS, telematics, domain controllers and vehicle computers.”
Inside is its eight generation 3D flash and an in-house designed controller – CMOS-directly-bonded-to-array constriction is used.
UFS4.1 is backward compatible with UFS4.0 and UFS3.1.
Compared with its UFS 3.1 THGJFGT2T85BAB5, said Kioxia, its 512Gbyte UFS 4.1 devices will deliver approximately: 2.1x sequential read performance, 2.5x sequential write, 2.1x random read and 3.7x random write.
Less than a month ago Kioxia began sampling non-automotive UFS 4.1 flash memory
