256GB Memory For Car Dashboards & ADAS

Samsung’s 256GB embedded Universal Flash Storage (eUFS) is now being shipped to automakers to support the demand of Advanced Driver Assistance Systems (ADAS), next-generation infotainment systems and new-age dashboards in luxury vehicles. The 256GB eUFS is supposed to be the first storage device with advanced features based on automotive specifications from the JEDEC UFS 3.0 standard.

The chip claims to extend the temperature range to between -40°C and 105°C for both operational and power-saving modes.

It follows the firm’s 128GB eUFS version launched in September last year.

A remarkable feature is the chip’s enhanced warranty for extended temperature range that is crucial for next-gen automotive memory applications. The chip claims to extend the temperature range to between -40°C and 105°C for both operational and power-saving modes.

In contrast, “warranties for conventional embedded multimedia card (eMMC) 5.1 solutions generally cover -25°C to 85°C for vehicles in operation and -40°C to 85°C when in idle or power-saving mode”, Samsung noted.

Not only an extended temperature range, the chip also has a temperature notification feature, wherein a sensor will notify the host application processor (AP) when the device temperature exceeds 105°C or any preset level. The AP would then regulate its clock speed to lower the temperature to an acceptable level.

Sequential reads for the 256GB eUFS can reach 850 megabytes per second (MB/s), which is at the high end of the current JEDEC UFS 2.1 standard, and random read operations come in at 45,000 IOPS, Samsung stated.

The chip also fulfils the data refresh features included in UFS specification, version 3.0, announced recently by JEDEC. This feature speeds up processing and enables greater system reliability by relocating older data to other less-used cells.
