HYBRID HARD DISK DRIVE, COMPUTER SYSTEM INCORPORATING HYBRID HARD DISK DRIVE, AND FLASH MEMORY DMA CIRCUIT FOR HYBRID HARD DISK DRIVE

摘要

PROBLEM TO BE SOLVED: To provide a hybrid hard disk drive, a computer system incorporating the hybrid hard disk drive, and a flash memory DMA (Direct Memory Access) circuit for the hybrid hard disk drive. SOLUTION: This hybrid hard disk drive has a flash memory. The flash memory has a main memory area storing user data and a spare memory area storing additional information necessary for transmission of the user data. The flash memory DMA circuit for the hybrid hard disk drive provides an interface with the flash memory as hardware. Thereby, overhead by interfacing with the flash memory can be reduced while materializing a short boot time and small power consumption. COPYRIGHT: (C)2008,JPO&INPIT
