Memory systems and operation methods thereof and storage devices and operation methods thereof

Abstract

Examples of the present disclosure disclose a memory system and an operation method thereof and a storage device and an operation method thereof. The memory system includes a memory device and a memory controller, the kmemory blocks in memory planes in the memory device form one super memory block, super memory blocks form one virtual memory block, the mphysical pages coupled with the nword lines in the memory planes from a same super memory block in the virtual memory block form one virtual physical page, the virtual physical pages from super memory blocks in a same virtual memory block form one strip; and the memory controller is configured to: receive memory data that needs to be written to a strip; generate parity check data of the strip according to the memory data; and send the memory data and the parity check data to the memory device.
