Market Overview Semiconductors play a pivotal role in China's state-backed investment in Market share held by leading NAND Flash memory cutting-edge memory chips. The "Made manufacturers worldwide in China 2025" initiative, unveiled three years ago, aims to upgrade the country's manufacturing sector. Yangtze Memory Technologies was poised to become China's first mass- producer of 3D NAND flash memory chips and TechInsights has now confirmed it’s presence. This will be sure to disrupt the 52 billion NAND Memory Market and its respective https://www.statista.com/statistics/275886/market-share-held-by-leading-nand-flash-memory- Market Leaders. manufacturers-worldwide/ 5 TechInsights CONFIDENTIAL.

YMTC 3D 64L Xtacking TLC NAND: Early Observations We have found 3D 64L Xtacking® TLC NAND devices manufactured by Yangtze Memory Technologies Co., Ltd. (YMTC). We are seeing 73 gates in total for a vertical NAND string with nine vertical Top-metal viewed die photo showing the very small/compact die with higher memory bit density channel (VC) holes, including one dummy hole between common source line contacts. It is likely that 5 select gates (1 SSG and 4 DSGs) and 4 dummy gates are also used.

YMTC Xtacking Architecture ▪ In Xtacking architecture, periphery circuits and memory cell operations are processed on a separate wafer, resulting in higher array efficiency and memory bit density than conventional 3D NAND solutions, such as Samsung 64L V-NAND and KIOXIA/WD 64L BiCS NAND. For example: ▪ YMTC 64L 256 Gb die bit density is 4.41 Gb/mm2 which is higher than Samsung 64L 256 Gb die (3.42 Gb/mm2), and comparable to Micron/Intel 64L CuA FG 256 Gb TLC die (4.40 Gb/mm2) YMTC Xtacking uses Wafer-to-Wafer hybrid bonding technology, meaning the NAND array is upside-down on periphery circuits. The process integration consists of: 1. Metal 1 through Metal 4 for periphery circuits on a wafer 2. NAND array with a source plate (SP) and Metal 1’ through Metal 3’ on a separate wafer 3. Wafer-to-Wafer hybrid bonding to connect M4 X-section SEM image along BL direction showing Xtacking architecture and Metal 3’ 4. Through SP Via and Metal 5.
