Abstract
Provided are a hybrid hard disk drive (HDD), a computer system including the hybrid HDD, and a flash memory DMA circuit for the hybrid HDD. The hybrid HDD includes a flash memory. The flash memory includes: a main memory region; and a spare memory region storing additional information necessary for transmitting user data stored in the main memory region. The flash memory DMA circuit of the hybrid HDD is used for interfacing the hybrid HDD with the flash memory. Therefore, rapid booting and low power consumption can be realized, while reducing overhead resulted from interfacing the hybrid HDD with the flash memory.
