Abstract

Examples of the present disclosure provide a memory device and an operation method thereof, a memory system and a storage medium. The memory device includes: a memory cell array, and a peripheral circuit coupled with the memory cell array, wherein the peripheral circuit is configured to: before performing a power on reset operation, set all state information of a plurality of main memory areas in a page buffer to a normal state; in the process of performing the power on reset operation, match a second address of each of the plurality of main memory areas with a first address in a register; and determine, according to a match result, whether to modify state information of a respective main memory area in the page buffer to a fault state.
