SEMICONDUCTOR STORAGE DEVICE MEMORY DISK UNIT WITH MULTIPLE HOST INTERFACES AND DRIVING METHOD

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.
