Abstract: Example embodiments of the present disclosure disclose method and system for performing read/write operations in NAND memory. A memory controller of the NAND memory receives write request from host controller to write data present in set of support cell blocks of NAND memory into a ‘n’-level cell block of NAND memory. The write request includes information about mapping between set of support cell blocks and ‘n’-level cell block. The mapping between set of support cell blocks and ‘n’-level cell block is used to update L2P table (206). Further, memory controller performs copyback operation on set of support cell blocks for writing data to ‘n’-level cell block based on L2P table using NAND latches. On receiving read request, host controller retrieves data from at least one support cell block associated with ‘n’-level cell block based on mapping on determining ‘n’-level cell block is listed in active block list.

Abstract: A non-volatile memory express over fabrics (NVMeoF) redundant array of independent disks (RAID) controller includes an NVMeoF RAID target module, an NVMeoF RAID implementation module, and an NVMeoF RAID initiator module. The NVMeoF RAID target module receives one or more NVMeoF commands from one or more computer hosts. The NVMeoF RAID implementation module receives the one or more NVMeoF commands from the NVMeoF RAID target module and performs RAID functionalities on the one or more NVMeoF commands The NVMeoF RAID initiator module receives the one or more NVMeoF commands from the NVMeoF RAID implementation module and transmits the one or more NVMeoF commands to the one or more storage target devices to establish one or more virtual queue pair connections and enable direct data transfer between the one or more computer hosts and the one or more storage target devices.
