CONTROLLER OF A NONVOLATILE MEMORY DEVICE AND A COMMAND SCHEDULING METHOD THEREOF

摘要

A controller which includes a working memory on which a command scheduler is loaded; and a processor configured to load at least one mapping table from a mapping table array onto the working memory. The command scheduler reorders commands provided from a host based on logical block addresses, and the processor loads at least one other mapping table onto the working memory according to logical block addresses of the commands reordered by the command scheduler.
