Tutorial 4: Introduction to Memory technology & Products
Speakers: Kalyan Kavalipurapu and Venkat Bringivijayaraghavan, (Micron Technology)
Tutorial Abstract:
DRAM and NAND memory products play a key role in transforming the data processed by the various and diverse compute, communication and AI/ML systems into intelligence. This tutorial will provide an introduction to the DRAM and NAND semiconductor memory technologies and product designs highlighting some of their characteristics and challenges.
Part 1: “All about NAND Flash Memory”
Abstract:
The tutorial gives an insight into the basics of NAND flash, operations of NAND flash, 2D planar NAND and its evolution to 3D Floating gate and Replacement gate technology. Also discussed are the innovative CMOS under array technology, NAND performances and error correction features.
