TrendForce pointed out that DRAM-related applications for vehicles are currently divided into four major areas, including in-vehicle infotainment systems (Infotainment), advanced driver assistance systems (ADAS), in-vehicle information systems (Telematics), and digital dashboards (D-cluster) .

However, the DRAM consumption of current commercial vehicles is still low. Only the in-vehicle infotainment system uses the most. Compared with the ADAS system, the entry barrier of this project is less restricted by vehicle safety or current regulations, which attracts many semiconductors. Get in with the storage factory.

TrendForce expects that in addition to in-vehicle infotainment systems will still be the main application of automotive DRAM consumption by 2024, as the level of self-driving increases, automotive DRAM bit consumption will account for 3% of overall DRAM bit consumption. Above, its follow-up potential should not be underestimated.

  

TrendForce further stated that since the safety requirements of automobiles are much higher than those of general consumer Electronic devices, the rigor of quality and durability cannot be compared. Therefore, it is possible for car dealers to start a new car, verify it, and actually market it. The gap of 3 to 5 years also makes the memory capacity and specifications of the current commercially available cars have a huge gap compared with the ones in the open case.

  The DRAM consumption of commercial vehicles is still low, and in-vehicle infotainment systems will still be the mainstream application in the future

From the perspective of in-vehicle infotainment systems, under the computing requirements of basic audio-visual entertainment, this project is currently the category with the highest DRAM usage among commercially available cars. However, because the function is still quite simple, the mainstream DRAM usage is only 1~2GB (Gigabyte), and with the upgrade of image quality and the increase of image transmission speed, the solution in the open project is shifting to 4GB and high-end towards 8GB. The trend of progress.

In terms of product specifications, due to the close visual distance of the in-vehicle infotainment system, the picture transmission delay time must be extremely short to prevent frustration. Under the requirements of speed and bandwidth, DRAM specifications have gradually moved closer to LPDDR4 8Gb from DDR3 2/4Gb (Gigabit).

From the perspective of advanced driver assistance systems, the current development can be divided into two systems, one is a divergent type such as a reversing radar, and its DRAM consumption is only 2/4Gb; the other is a centralized type, which intercepts each sensor The received information is directly sent back to the central control for integration and calculation, using 2/4GB of higher DRAM usage.

However, the current vehicles on the market are still dominated by ADAS level 1~2, so the DRAM consumption is still low. In the future, with the development of self-driving levels above level 3, and even the addition of AI functions, since vehicles must have the ability to integrate information and make judgments immediately, the large amount of data captured by sensors must be processed in real time, so the bandwidth requirements are also greater. Big, it will drive the evolution of DRAM specifications from DDR3, to LPDDR4/4X, and then to LPDDR5, and even GDDR6/HBM. However, considering the current regulatory factors, it may still take time to achieve.

From the perspective of in-vehicle information systems and digital dashboards, the former is the communication system of the vehicle. The current mainstream memory is all MCP solutions. Since this system is highly related to the base frequency, they are all equipped with LPDRAM.

In the future, with the increasing necessity of vehicle-to-vehicle interconnection and communication (V2V) and Internet of Vehicles (V2X), memory bandwidth will be an important consideration. DRAM specifications will gradually be introduced from the previous LPDDR2 to LPDDR4/LPDDR5, but its growth rate will be It depends on the rise of 5G infrastructure, because it relies on 5G networks to perform point-to-point series connection.

In the last part of the digital dashboard, the DRAM usage is only 2/4Gb, which varies according to the degree of digitization of the dashboard. However, the growth rate of the DRAM usage in this category in the future is not high, and the future may be integrated with the car infotainment system into a central control system.
