Raja Koduri's mission to deliver high bandwidth memory for GPUs has taken a turn that could enable 4TB of VRAM on AI cards — joins Sandisk to advise on SSD tech that could feed AI accelerators

Raja Koduri in Taipei, 2025.

Raja Koduri continues to push his high bandwidth vision for computing, but this time it's flash, namely HBF (High-Bandwidth Flash) from Sandisk. On Wednesday, the former graphics architect at S3, Apple, AMD (twice), and Intel, announced that he had joined Sandisk’s HBF Technical Advisory Board to guide development and strategy for High-Bandwidth Flash memory technology. Sandisk also shared a press release confirming Koduri’s new role, as well as the appointment of Professor David Patterson to the board.

Excited to partner with Sandisk.When we began HBM development our focus was improving bandwidth/watt and bandwidth/mm^2 (both important constraints for mobile), while maintaining competitive capacity with the incumbent solutions. With HBF the focus is to increase memory…July 24, 2025
