Automotive flash memory refers to a specific type of flash memory technology that is designed and qualified for use in automotive applications. It plays a crucial role in various aspects of modern automotive systems, offering real-world benefits in terms of reliability, performance, and data storage.
Automotive flash memory is found in the electronic control units (ECUs) used in today’s vehicles. These ECUs are responsible for managing various functions within the car, including engine control, transmission, infotainment systems, and safety features. Automotive flash memory is used to store the firmware and software that run on these ECUs
The device achieves 20 times faster random read transactions for real-time applications and performs 8 times better than conventional NOR Flash memory. This makes it possible for software-defined cars to offer cutting-edge features with improved security and architectural flexibility.
At these advanced nodes, higher density embedded non-volatile memories are no longer a financially viable alternative, hence system builders should think about employing external NOR for code storage. However, these sophisticated automotive real-time computers require greater performance than what is currently offered in memory.
Future automotive applications, such as electric or autonomous vehicles, can manage battery life more effectively thanks to the improved portfolio. For instance, the 256GB model provides a 33% reduction in energy consumption when compared to the previous model. Additionally, the 256GB variant offers a 700 MB/s sequential write performance and a 2,000 MB/s sequential read speed.
Advanced mobile functions that were before only available in pricey flagship smartphones employing discrete products, such as stand-alone memory and storage, are now powered by the multi chip package from Micron, which also uses high-reliability NAND and a cutting-edge UFS 3.1 controller.
These cutting-edge features, such image recognition, powerful artificial intelligence (AI), multi camera support, augmented reality (AR), and high-definition screens, are now accessible on other high-end phones, making them more widely available to users.
Performance requirements are also similar in that early models must support music players and navigation map use. However, the internal interface has been upgraded to a faster UFS interface EFD, which provides full duplex transfer and effectively lowers read and write data latency. With higher bandwidth, the most recent UFS V4.0 2L standard has an improved bandwidth of 5.8GB/s.
By adding six automotive-grade devices to its flash memory lineup, Spansion Inc. bolstered its offering of automotive flash memory. Three new Serial NOR and three new NAND memory densities are being added by Spansion, and they are both specifically suited to handle the wide temperature ranges and exacting quality standards of the automobile industry.
“Spansion has maintained its leadership in automotive flash devices for more than 20 years with extensive range of automotive-grade flash memories and proven quality, technical support, and product life, Spansion Flash Memory Group. “
As applications like Advanced Driver Assistance Systems (ADAS), instrument clusters, entertainment, and data recording systems become standard offerings in a larger range of cars, automotive OEMS are increasing their demand for automotive grade components.”
“Devices that adhere to PPAP and are automotive-grade with AEC-Q100 accreditation satisfy the strictest standards established by automakers globally. The market leadership of Spansion is a result of their active involvement in the development, testing, delivery, and support of high-performance, high-quality embedded systems for the automobile industry.”
Automotive grade flash memory is perfect for industrial uses such as solar inverters, power switches, factory automation, and safety monitoring equipment in addition to automotive applications.
The Global Automotive flash memory market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
One-transistor 90-nanometer MONOS flash memory technology has been developed by Renesas Electronics and is compatible with a number of different technologies, including CMOS and bipolar CMOS DMOS. The program/erase durability is high, and the rewrite energy consumption is low.
A new generation of Automotive Universal Flash Storage Ver. 3.1 embedded flash memory devices are now being sampled, according to Kioxia Corporation. To suit the different needs of developing automotive applications, the new line-up makes use of the company’s BiCS FLASH 3D flash memory and is offered in capacities ranging from 64 GB to 512 GB.
For automotive applications, Toshiba Corporation has introduced 15nm eMMC NAND flash memory. The vehicle e?MMC from Toshiba has a wide operating temperature range of -40°C to 85°C, a JEDEC standard package of 11.5x13mm, and great reliability.
Renesas Electronics Corporation has chosen Macronix International Co., Ltd.’s MX25UW51245G Serial NOR Flash memory for reference designs based on the Vehicle Computer Generation 4 chipset. The Renesas R-Car S4 system on a chip based VC4 platform will receive crucial memory from the high-performance MX25UW51245G.
Regarding financial and operational aspects, the pandemic has caused havoc on a number of industrial verticals, including the global automotive memory market participants. When the World Health Organization (WHO) declared the coronavirus outbreak pandemic, nations all around the world imposed temporary lockdowns and travel restrictions.
While limiting people’s freedom of movement, such restrictions had a significant negative impact on automotive production and sales around the world. it saw a decline in the number of vehicles being purchased, which had a corresponding effect on the need for automotive memory.
Production facilities for automobiles and their components had to close all over the world, car dealership traffic dropped, and temporary trade restrictions were imposed by governments in many different regions. These issues also contributed to a sharp fall in automotive sales in high growth nations.
