Abstract
A peripheral circuit of a memory device includes page buffers. Each page buffer includes a main latch, a bias latch, (N−1) data latches, and a cache latch coupled to a data path. The peripheral circuit is further configured to: in the process of programming a first physical page, disable a bit line bias function to release the bias latch to replace one of N page latches to perform a programming verification of memory states; release one of the N page latches to cache program data of one of the N logical pages of a second physical page; and in the process of programming the first physical page, store the program data of the one of the N logical pages of the second physical page in a released page latch.
