From PC World: SSDs are about to get a whole lot bigger and a whole lot cheaper. Intel and Micron on Monday afternoon announced the delivery of the industry's first Quad-Level Cell NAND dies, which will offer a third more space than previous technology.
QLC technology stores four bits per cell on a NAND cell, which is a significant increase over today's common TLC (Triple-Level Cell) NAND.
SSD capacity has grown gradually. The first SSDs used Single-Level Cell and stored a single-bit per cell. That moved to two-bits per cell with Multi-Level Cell, and to 3-bits per cell with Triple-Level Cell technology. With QLC, Intel and Micron have achieved the next step.
"With introduction of 64-layer 4bits/cell NAND technology, we are achieving 33 percent higher array density compared to TLC, which enables us to produce the first commercially available 1 terabit die in the history of semiconductors," said Micron Executive Vice President, Technology Development, Scott DeBoer. "We’re continuing flash technology innovation with our 96-layer structure, condensing even more data into smaller spaces, unlocking the possibilities of workload capability and application construction."
