Abstract
A storage device is disclosed herein. The storage device comprises: a non-volatile memory, where the non-volatile memory includes a block of N wordlines partitioned into a plurality of sub-blocks and the plurality of sub-blocks includes a first sub-block of a first subset of the block of N wordlines and a second sub-block of a second subset of the block of N wordlines; and control circuitry coupled to the block of N wordlines. The control circuitry is configured to: perform a program operation in a normal order programming sequence on the first sub-block; perform a sensing operation on the first sub-block using a reverse sensing scheme; perform a program operation in a reverse order programming sequence on the second sub-block; and perform a sensing operation on the second sub-block using a regular sensing scheme.
