The landscape of in-vehicle technology is undergoing a significant transformation, driven by the relentless demand for more sophisticated and reliable systems. At the forefront of this evolution, Kioxia, a global leader in memory solutions, has made a pivotal announcement, initiating the sampling of its cutting-edge Universal Flash Storage (UFS) Ver. 4.1 embedded memory devices specifically engineered for automotive applications.
These innovative UFS 4.1 devices represent a crucial leap forward, meticulously designed to satisfy the rigorous performance and durability requirements of future automotive systems. They promise substantial enhancements in speed, flexibility, and diagnostic capabilities, critical for the complex computational demands of autonomous driving, advanced infotainment, and connected car functionalities. This new generation of automotive memory is set to empower a new era of intelligent vehicles.
Central to the superior performance of these Kioxia UFS 4.1 devices is the integration of the company’s advanced Generation 8 BiCS FLASH™ 3D flash memory, coupled with Kioxia’s proprietary in-house designed controller technology. This powerful combination ensures optimal data management and reliability, essential for the high-stakes environment of automotive electronics where consistent performance is paramount.
A hallmark of Kioxia’s Generation 8 BiCS FLASH™ technology is the introduction of revolutionary CBA (CMOS directly Bonded to Array) technology. This architectural breakthrough signifies a monumental shift in flash memory design, where the CMOS circuitry is directly bonded to the memory array. This direct bonding dramatically improves power efficiency, boosts overall performance, and allows for higher data density within a smaller footprint, making these embedded memory solutions incredibly efficient.
Kioxia has already commenced sample shipments of these advanced automotive memory devices, with the 1TB variant beginning in June, followed by 128GB and 256GB devices in July. It is important for potential integrators to note that specifications for these samples may vary slightly from the eventual commercial products, allowing for fine-tuning based on early feedback and application-specific needs.
Universal Flash Storage, or UFS, is a standardized product category for embedded memory built to the JEDEC UFS specification. Its serial interface is a key differentiator, enabling full duplexing capabilities. This allows for simultaneous reading and writing between the host processor and the UFS device, significantly accelerating data throughput and responsiveness – a critical advantage for real-time automotive operations.
Kioxia, a titan in memory solutions, is dedicated to the development, production, and sale of high-performance flash memory and solid-state drives (SSDs). The company’s heritage traces back to 2017 when its predecessor, Toshiba Memory, spun off from Toshiba Corporation, the pioneering entity behind NAND flash memory in 1987. Kioxia’s overarching mission is to enrich the world through “memory,” delivering products and systems that offer unparalleled choice and value.
The innovative BiCS FLASH™ 3D flash memory technology by Kioxia is not only shaping the future of automotive systems but is also foundational to high-density applications across various sectors. Its impact is profoundly felt in advanced smartphones, personal computers, high-performance SSDs, data centers, and the burgeoning field of generative AI systems, underscoring its versatility and critical role in modern digital infrastructure.
