Samsung has introduced that it has began mass manufacturing of eUFS 2.1-compatible storage units for automotive purposes. The brand new 256 GB units help choose UFS three.zero options for automobiles, are certified to function in excessive temperature ranges and provide efficiency ranges on par with at this time’s smartphones.
Samsung’s new 256 GB eUFS machine relies on the corporate’s planar MLC NAND flash reminiscence produced utilizing a 10 nm-class course of expertise in addition to a proprietary UFS 2.1 controller supporting knowledge refresh and temperature notification capabilities — each applied sciences are part of the united states3.zero specification launched final month and each are supported by Samsung’s 64 GB and 128 GB eUFS merchandise for automotive purposes in addition to by competing units. The 256 GB eUFS chip is assured to retain knowledge and function in excessive temperature situations — between -40°C and 105°C (i.e., they’re AEC-Q100 Grade 2 compliant). Such working ranges be sure that a automobile’s ADAS and infotainment methods powered by Samsung’s newest eUFS machine can survive chilly winters (however not excessive ones with temperatures round -50°C) in addition to Iran’s Lut desert (the place 70°C appears to be frequent). The storage product has an built-in thermal sensor, so when its temperature hits the utmost degree (or any pre-set degree), the storage machine will notify the host processor, which in flip will regulate its frequency to decrease the temperature.
Efficiency of Samsung’s eUFS 256 GB machine for automotive purposes is on the high-end of the united states2.1 spec and may ship as much as 850 MB/s sequential learn pace in addition to as much as 45Ok random learn IOPS. Sadly, the producer doesn’t disclose all efficiency and any endurance specs of its eUFS 256 GB machine, however the present figures are in-line with efficiency of storage options for at this time’s smartphones in addition to with entry-level PCIe SSDs. In the meantime, Samsung says that its refresh functionality that relocates knowledge from cell to cell to maintain expenses at ample ranges to increase knowledge retention additionally has a constructive impact on efficiency as host processors would not have to extensively use learn retry operation due to decrease quantity of learn errors.
Samsung has already began to ship its 256 GB eUFS 2.1-compliant units to its companions amongst automotive producers engaged on next-generation ADAS (superior driver help methods), infotainment methods, and dashboards. Samsung doesn’t identify the respective producers, however claims that the 256 GB UFS 2.1 will first be used for high-end automobiles.
