Abstract
Open block-based read offset compensation in read operation of memory device is disclosed. For example, a memory device includes an array of memory cells arranged in a plurality of blocks and a peripheral circuit coupled to the array of memory cells. The peripheral circuit is configured to, in response to a block of the plurality of blocks being an open block, perform a read operation on a memory cell of the array of memory cells in the block using a compensated read voltage. The compensated read voltage has an offset from a default read voltage of the block.
