SEMICONDUCTOR STORAGE DEVICE MEMORY DISK UNIT INCLUDING A PLURALITY OF HOST INTERFACES AND OPERATING METHOD THEREOF FOR CONNECTING A SEMICONDUCTOR STORAGE DEVICE MEMORY DISK UNIT TO A HOST INTERFACE

摘要

PURPOSE: An SSD(semiconductor storage device) memory disk unit including a plurality of host interfaces and operating method thereof are provided to support a low data processing speed by controlling the synchronization of data signals transmitted and received between a host and a memory disk.;CONSTITUTION: Host interface units(202A-202N) connects an SSD memory disk unit to a host. A host interface controller unit(301) is connected to the host interface units. A DMA(dynamic memory access) controller(302) is connected to the host interface controller unit. An ECC(error check and corrector) controller(304) is connected to the DMA controller. A memory controller(306) is connected to the ECC controller. A memory array is connected to the memory controller and includes an SSD memory block set.;COPYRIGHT KIPO 2013;[Reference numerals] (202A) Host interface 1; (202N) Host interface N; (301) Host interface controller; (302) DMA controller; (304) ECC controller; (306) Memory controller; (600A) Backup storage unit; (602) Memory; (700) Backup controller
