COMPUTER SYSTEM HAVING A PARTITIONED FLASH TRANSLATION LAYER AND FLASH TRANSLATION LAYER PARTITION METHOD THEREOF

摘要

A computer system having a partitioned FTL(Flash Translation Layer) and a method of partitioning an FTL are provided to enable effective resource utilization while reducing the complexity and load of a flash controller. A computer system includes a host, a flash memory device and a flash controller(420). The flash controller controls the flash memory device in response to a read/write request from the host. At least one of functional modules of an FTL for managing the flash memory device is executed by the host and the other modules are executed by the flash controller. The host processes data according to an operating system. The operating system includes a file system(410) which executes at least one of a plurality of functional modules constituting the FTL.
