How to set MLC_MODE in GreedyFTL-2.7.1.d project

Post by shengwenLiang » Wed May 23, 2018 5:20 am

Hi,
Today, I change BIT_PER_FLASH_CELL from SLC_MODE to MLC_MODE in init_ftl.h, and after run firmware, I find the storage capacity is 124296 MB, and if I use SLC_MODE, the storage capacity 124056 MB. why the storage capacity only increase 240MB?
where should I modify except BIT_PER_FLASH_CELL to support MLC_MODE pattern?
Thanks

The storage capacity is limited because the system memory is not enough to contain the entire mapping table. You might need some additional scheme such as DFTL and MapCache.
