  "account": "Kioxia and SanDisk have unveiled a groundbreaking chip that could enable the first 1 petabyte (1,000 terabyte) solid-state drive (SSD) for data centers. The Quad-Level-Cell (QLC) 3D flash memory chip, developed in collaboration with Kioxia, employs a novel CMOS directly Bonded to Array (CBA) technology. This technology allows for a significant 60% increase in bit density compared to previous generations of 3D flash memory.\n\nThe chip achieves a density of 37 Gb/mm² and can transfer data at an impressive 4.8 Gb/s interface, setting a new benchmark for performance and power efficiency. While the size of the chips makes their implementation impractical for home systems, they are well-suited for ultra-dense 1U and 2U rack servers in data centers.\n\nThis development, according to SanDisk's CTO Alper Ilkbahar, is a crucial step towards implementing AI across the connected world. The chip's high density will enable efficient storage for rapidly expanding data volumes, supporting the needs of agent-based, physical AI, and generative AI applications. Kioxia's CTO Hideshi Miyajima adds that QLC technology is essential for delivering greater performance and scalability for AI systems.\n\nThe announcement suggests that a 1 PB SSD from Kioxia and SanDisk could be available as early as 2027, ahead of any potential 1 PB SSD from Samsung, which is approaching the challenge using a higher number of layers in ultra-tall stacks.",
