DRAM-PIM Architectures: Challenges, Solutions and Efficiency

Abstract

Emerging applications such as Deep Neural Networks are data driven and memory intensive. Hence, there is a recent shift from compute centric architectures to memory centric architectures. Processing-in-Memory (PIM) is a new promising memory-centric compute paradigm. Recently, we are witnessing a surge in DRAM-PIM publications from both academia and industries. The underlying DRAM-PIM architectures range from modifying the highly optimized DRAM sub-arrays to enable computations to straightforward integration of the computation units in the DRAM/IO region. In this talk we give an overview on DRAM-PIM architectures, highlight challenges and present novel architectures.
