Due to the advent of the Internet of Things (IoT), the prevalence of social networking services (SNSs), and production of photos and videos at ever-higher resolution, the volume of data generated worldwide is growing exponentially.
In the field of information processing, real-time performance is considered an important requirement as a huge amount of data must be managed by big-data systems or indefinitely stored by data centers and cloud service systems. In this situation, high-capacity storage is required to process, store and manage large quantities of data at high speed and low power consumption.
Furthermore, for smartphone, tablet, memory card and other power-sensitive applications, demand for storage with lower power consumption is increasing.
BiCS FLASH, which offers many advantages over planar NAND flash memory, will be the solution satisfying the market requirements.
Features of BiCS FLASH
High Density and High Capacity
The vertically stacked three-dimensional (3D) flash memory, BiCS FLASH, has far higher die area density compared to the prior state-of-the-art technology, two-dimensional (2D) NAND flash memory. Moreover, BiCS FLASH reduced the chip size by optimizing both circuit technology and manufacturing process.
Fast Programming Speed
Spaces between memory cells in BiCS FLASH are far wider than in 2D NAND flash memory. This made it possible to improve the programming speed by increasing the amount of data for a single-shot programming sequence.
BiCS FLASH’s wide open spaces between memory cells reduce cell coupling and improve reliability compared to the 2D NAND flash memory.
