Cost-efficient memory architecture design of NAND flash memory embedded systems

摘要

NAND flash memory has become an Indispensable component in embedded systems because of its versatile features such as nonvolatility, solid-state reliability, low cost and high density. Even though NAND flash memory gains popularity as data storage, it also can be exploited as code memory for XIP (execute-in-place). We present a cost-efficient memory architecture, which incorporates NAND flash memory into an existing memory hierarchy for code execution. The usefulness of the proposed approach is demonstrated with real embedded workloads on a real hardware prototyping board.
