This article provides a detailed exploration of BiCS8’s technological breakthroughs.

 

What is BiCS8? Understanding the Eighth Generation of BiCS

 

BiCS8 refers to BiCS Flash, a type of 3D NAND Flash technology, where the '8' represents the eighth generation. BiCS8 adopts a 3D vertical stacking architecture, expanding storage capacity while also increasing the distance between memory cells, which minimizes interference and improves both processing speed and power efficiency. Compared to traditional 2D NAND Flash, BiCS8 also shows significant improvements in write performance, stability, and power usage.

With the BiCS8 generation, performance, density, and efficiency are elevated to new levels. It adopts an advanced 4-Plane Architecture and ultra-high-speed I/O interface to enhance data access speed. Furthermore, the 218-layer stacking combined with CMOS directly Bonded to Array (CBA) wafer bonding technology increases storage capacity per unit and offers better cost efficiency. Compared with BiCS5, BiCS8 achieves an 80% increase in interface speed and faster read/write performance, enhancing scalability and overall efficiency for high-load industrial and embedded applications, while establishing a foundation for next-generation storage technologies.

 

Understanding BiCS8 Core Technologies and Advantages

 

As just mentioned, BiCS8 brings advancements across multiple dimensions. From interface speed and read/write performance to storage capacity and stability under high-temperature conditions, it surpasses the previous generation. Here, we take a closer look at the core technologies that power BiCS8’s capabilities.

 

218-Layer Stacking Structure

 

BiCS8 employs a 218-layer vertical stacking structure, boosting memory density by 50% compared with BiCS5. This allows a single chip to store significantly more data, delivering higher storage capacity without increasing cost.

 

High-Speed I/O and 4-Plane Architecture

 

BiCS8 employs a 4-Plane Architecture, with each plane featuring its own Cache Register and Page Register. Parallel data access across multiple planes, combined with an I/O speed of 2400/3600 Mbps, which represents an 80% increase over its predecessor, enhances data transfer and access capabilities, reduces latency, and improves read/write performance.

 

CMOS Bonded to Array (CBA)

 

BiCS8 uses CMOS Directly Bonded to Array (CBA) technology, where the logic circuits that control the memory and the NAND memory array that stores the data are built on separate wafers. These wafers are then joined using copper-to-copper bonding, a design that enhances both storage scalability and overall efficiency.

 

Enhanced Read/Write Performance

 

Thanks to multiple technological innovations, BiCS8 achieves a 45% increase in write speed and reduces read latency by more than 10%, resulting in faster data access.

 

Increased Operating Temperature

 

In addition to enhanced performance, BiCS8 features an operating temperature of up to 85°C, ensuring reliable and stable operation across a wide range of demanding industrial environments.

It is clear that BiCS8's core technologies result in high read/write performance and storage efficiency, strong scalability, and the ability to handle various demanding industrial environments. It is particularly suitable for use in edge devices for smart manufacturing, transportation systems, or industrial control (IPC) embedded platforms. Therefore, adopting BiCS8 storage solutions can effectively meet the challenges of future high-performance computing while maintaining stable long-term performance. Next, we will introduce BiCS8's practical applications and features in different fields.

 

Industrial Automation Equipment

 

In smart factories, edge devices often need to bear the task of real-time processing of large amounts of sensor data. If the storage solution is insufficient in performance or write endurance, it may lead to data delay, corruption, or system anomalies. BiCS8's high sustained write capability and its ability to adapt to high-temperature environments allow it to demonstrate high-speed access and high-endurance features, making it suitable for deployment in devices such as PLCs, industrial PCs, and data recorders.

 

Transportation System

 

The transportation system places stringent requirements on storage components, necessitating resistance to high temperatures, significant vibration, and other environmental factors. BiCS8 supports an operating temperature up to 85°C, making it suitable for applications such as ADAS, digital dashboards, and in-vehicle infotainment systems.

 

Networking and Edge Computing Equipment

 

Networking and edge computing equipment, such as 5G base stations and edge servers, are sensitive to I/O throughput and latency. BiCS8’s high I/O speed of 2400/3600 Mbps and its low-latency characteristics help systems enhance reaction speed and performance.

 

AIoT Devices

 

AIoT applications like smart surveillance and smart city sensors typically require real-time data analysis and storage on the device end. Therefore, there are high demands for the storage device's performance, density, and stability. BiCS8’s high-density and high-performance design perfectly supports the running of complex models and data caching.
