The companies will produce state-of-the-art 3D flash memory using technology developed together as part of an effort to satisfy rising demand for flash memory used in systems that power artificial intelligence (AI) functionalities.

"As AI advances, it is poised to transform industries, redefine careers, and reshape daily life in ways we're just beginning to imagine," said Maitreyee Mahajani, senior vice president of flash front end operations at Sandisk.

"Flash memory is at the very center of this transformation, unlocking the speed, efficiency and scalability needed for this next wave of innovations," she said.

A sideways AI play

Although there has been some pullback at times from stocks most directly associated with AI, there's life in some that aren't so readily identified with the technology. Sandisk is a veteran flash memory producer, and a compelling choice as a pick-and-shovel play in the flash segment of the AI space.
