3D NAND: Who Will Make It and When?

(The following is an update of a post that originally ran on 13 December 2013. It was republished in 2024 as a part of a series on The Memory Guy blog to honor the 3D NAND inventors who have received the 2024 FMS Lifetime Achievement Award.)

This series, originally run in 2013, has looked at 3D NAND technology in a good deal of technical depth. At that time, the last question to be answered centered around the players and the timing that the technology would Continue reading “3D NAND: Who Will Make It and When?”

Some of my readers have asked: “How is 3D NAND Continue reading “How Do You Erase and Program 3D NAND?”

An Alternative Kind of Vertical 3D NAND String

(The following is an update of a post that originally ran on 8 November 2013. It was republished in 2024 as a part of a series to honor the 3D NAND inventors who have received the 2024 FMS Lifetime Achievement Award.)

My prior 3D NAND post explained how Toshiba’s BiCS cell works, using a silicon nitride charge trap to substitute for a floating gate. This post will look at an alternative Continue reading “An Alternative Kind of Vertical 3D NAND String”
