The Journey of DRAM Continues

The Journey of DRAM Continues
by Arabinda Das on 09-26-2021 at 10:00 am

HBM

The field of DRAM is fascinating as it continues to grow and innovate. For the past ten years, I have often read that DRAM is running out of steam because of its difficulty to scale the capacitor, and yet it continues to evolve since invented by Dr. R. Dennard at IBM. In 1966, he introduced the concept of a transistor memory cell consisting… Read More
