报告内容简介:
Flash memory is driving a storage revolution with its pervasion in our daily lives. It can be found everywhere from consumer electronics such as cell phones, cameras, USB flash drives, TVs and toys to enterprise storage systems such as SSDs and enterprise flash drivers. In this talk, I will introduce our recent work in flash memory management for embedded systems. In particular, three techniques: Real-Time-FTL (Real-time NANF Flash Translation Layer), DAC (Demand-based block level Address mapping scheme with two-level Caching mechanism), and 3D-FlashMap (A Physical-Location-Aware Block Mapping Strategy for 3D NAND Flash Memory), will be presented. In Real-Time-NFTL, we present a flash translation layer that can greatly improve both the worst-case and average response time. In DAC, we propose a novel demand-based block-level address mapping scheme with two-level caching mechanism for large-scale NAND flash storage systems, so the RAM footprint can be greatly reduced without sacrificing too much system response time. In 3D-FlashMap, we propose a novel physical-location-aware block mapping strategy for three dimensional NAND flash memory. 3D-FlashMap can permute the physical mapping of blocks and maximize the distance between consecutively logical blocks, which can significantly reduce the disturbance to adjacent physical pages and effectively enhance the reliability.
