NEO Semiconductor won the 'Best of Show Award - Most Innovative Flash Memory Startup' in Flash Memory Summit Conference in Novermber 2020.
3D NAND flash memory is the main data storage device used in smartphones, solid state drives, cloud, data centers, memory cards, USB drives, IoT devices, drones, and AI robots. X-NAND is a revolutionary 3D NAND flash memory architecture. It can provide 3 times faster speed and more than 10 times of data throughput than the conventional NAND flash, without increasing any cost or footprint. This provides a high-speed, low-cost solution for 5G, AI, and many applications.
X-NAND is a revolutionary 3D NAND flash memory architecture. The traditional 3D NAND flash memory has only 2 - 4 planes in Y-direction. X-NAND architecture can increase the number of planes to 16 - 64 without increasing chip size. This reduces the bit line delay to only 1/4 - 1/32. It also allows 4 - 32 times of more data to be transferred in parallel. This drastically increases the speed performance of 3D NAND flash memory.
X-NAND architecture divides the array into 16-64 planes. This reduces the bit line length and capacitance to only 1/16-64, and increases the random read and write speed by 3-12 times.
The conventiona 3D NAND flash memory has only 2-4 planes due to the layout size of page buffers. The large bit line capacitance causes very slow speed for read and program-verify operations.
X-NAND architecture has 16-64 planes that allows 16-64 pages of data to be read and written in parallel. This increases the read and write data throughput by 8-32 times compared with the conventional 2 planes.
Conventiona NAND flash memory has only 2-4 planes, due to the constraint of page buffer layout size. Therefore, it can only read or write 2-4 pages in parallel.
X-NAND achieves 3X random read & write speed, 27X sequential read speed, and 15X sequential write speed of the conventional NAND flash memory, while it does not increase any chip size or manufacturing cost.
X-NAND architecture is a big breakthrough of 3D NAND flash memory technology. It provides an excellent high-performance and low-cost solution to fulfill the high-speed requirements for 5G and AI era.
NEO Semiconductor has been honored by CIOReview magazine as one of “10 Most Promising Semiconductor Technology Solution Providers - 2021" and featured as the cover story of the annual Semiconductor Technology edition.
