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 may alternatively or additionally include a storage device and a main processor. The main processor is configured to logically partition a plurality of non-volatile memory chips that are 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.

Dependencies are inferred from the claim text.
