Samsung introduced right this moment that it had begun mass manufacturing of its presumably 236-layer three-dimensional NAND reminiscence, which the corporate manufacturers as its eighth Era V-NAND. The brand new ICs characteristic a 2400 MTps switch pace, and when mixed with a sophisticated controller, they will allow client-grade SSDs with a switch pace of over 12 GBps.
The brand new eighth Era V-NAND system incorporates a 1Tb capability (128GB), which Samsung calls the business’s highest bit density with out disclosing the scale of the IC or the precise density. The IC additionally incorporates a 2400 MTps information switch fee, which is significant for one of the best SSDs that includes a PCIe 5.0 x4 interface that can provide blazing 12.4 GBps (or extra!) as soon as paired with an acceptable controller.
Samsung claims that the brand new technology of its 3D NAND reminiscence will provide a 20% greater per-wafer productiveness in comparison with its present flash ICs of the identical capability, one thing that lowers the corporate’s prices (offered the identical yields), which probably means cheaper SSDs.
In the meantime, the corporate says nothing concerning the system’s structure, however based mostly on the picture equipped, we assume we’re speaking a couple of dual-plane 3D NAND IC.
“As market demand for denser, greater-capacity storage pushes for greater V-NAND layer counts, Samsung has adopted its superior 3D scaling know-how to cut back floor space and top, whereas avoiding the cell-to-cell interference that usually happens with cutting down,” mentioned SungHoi Hur, Govt Vice President of Flash Product & Expertise at Samsung Electronics. “Our eighth-generation V-NAND will assist meet quickly rising market demand and higher place us to ship extra differentiated merchandise and options, which can be on the very basis of future storage improvements.”
Samsung has not introduced any precise merchandise based mostly on its eighth gen V-NAND reminiscence, but we will presume that the primary units will cater to shopper functions.
