On August 13, memory chip giant Sandisk (NASDAQ: SNDK) held its annual investor day, putting its in-house HBF technology front and center. The focus of the presentation was clear: management wanted to draw a line in the sand for gross margin, and that number is 80%.
For a memory chipmaker, an 80% gross margin isn't a number thrown out casually—it usually signals a shift toward higher value-add product lines, and HBF is seen as the key chip supporting that goal. As for HBF's specific technical architecture, use cases, and mass production timeline, publicly available materials haven't provided further detail.
