Apparatuses and methods providing redundant array of independent disks access to non-volatile memory chips
Abstract:
A controller may include a RAID controller and an access controller. The RAID controller exchanges data with a host and select ones of a plurality of RAID levels responsive to RAID level information. The access controller is connected to the RAID controller and to a plurality of channels that are each connected to a plurality of non-volatile memory chips. The access controller accesses data in at least one of the non-volatile memory chips connected to each of the channels according to the selected RAID level. The controller can include a storage device and a main processor. The main processor logically partitions a plurality of non-volatile memory chips connected to each of a plurality of channels into a normal partition region and a RAID level partition region, where data access is performed according to a selected RAID level, in response partition information that is stored in the storage device.
Abstract(Chinese):

控制器可以包括RAID控制器和访问控制器。 RAID控制器与主机交换数据，并根据RAID级别信息选择多个RAID级别中的一个。 访问控制器连接到RAID控制器和连接到多个非易失性存储器芯片的多个通道。 访问控制器根据所选择的RAID级别访问连接到每个信道的至少一个非易失性存储器芯片中的数据。 控制器可以包括存储设备和主处理器。 主处理器将连接到多个信道中的每一个的多个非易失性存储器芯片逻辑地划分为正常分区区域和RAID级别分区区域，其中根据所选择的RAID级别执行数据访问，响应分区信息， 存储在存储设备中。
