A multi-channel architecture for high-performance NAND flash-based storage system
نویسندگان
چکیده
Many mobile devices demand a large-capacity and high-performance storage system in order to store, retrieve, and process large multimedia data quickly. In this paper, we present a high-performance NAND flash-based storage system based on a multi-channel architecture. The proposed system consists of multiple independent channels, where each channel has multiple NAND flash memory chips. On this hardware, we investigate three optimization techniques to exploit I/O parallelism: striping, interleaving, and pipelining. By combining all the optimization techniques carefully, our system has shown 3.6 times higher overall performance compared to the conventional single-channel architecture. 2007 Elsevier B.V.

A High-Performance Solid-State Disk with Double-Data-Rate NAND Flash Memory
We propose a novel solid-state disk (SSD) architecture that utilizes a double-data-rate synchronous NAND flash interface for improving read and write performance. Unlike the conventional design, the data transfer rate in the proposed design is doubled in harmony with synchronous signaling. The new architecture does not require any extra pins with respect to the conventional architecture, thereb...
