a low-cost memory architecture with nand xip for mobile embedded systems
NAND flash memory has become an indispensable component in mobile embedded systems because of its versatile features such as non-volatility, solid-state reliability, low cost and high density. Even though NAND flash memory is gaining popularity as data storage, it can be also exploited as code memory for XIP (execute-in-place). In this paper, we present a new 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 prototyping board.
