摘要:
A non-volatile memory device includes a memory cell array having a plurality of memory cells programmable into one of multiple logic states, the plurality of memory cells disposed at intersections of a plurality of wordlines and a plurality of bitlines, and a plurality of page buffers respectively connected to the plurality of bitlines and performing verifying read operations on the plurality of memory cells. The verifying read operations are performed on a first memory cell having a target state and a second memory cell having a lower state than the target state.
摘要:
A nonvolatile memory device with a memory cell array including a plurality of memory cells coupled to first through M-th wordlines and first through N-th bitlines (M>2, N>2), and a page buffer circuit including first through N-th page buffers that are coupled to the first through N-th bitlines, respectively, and generate first through N-th output data, respectively. A K-th page buffer includes first through L-th latches which generate read data by sampling a voltage of a K-th output line, which is discharged through a K-th bitline, at different sampling timings after a read voltage is applied to a P-th wordline (K≦N, L>1, P≦M). The K-th page buffer outputs the first output data if an error in the read data of the first latch is correctable.
摘要:
A memory device is provided as follows. A memory cell array includes a plurality of memory cells, and the plurality of memory cells are divided into a first memory group and a second memory group. A first page buffer group is coupled to the first memory group and includes a plurality of first page buffers. A second page buffer group is coupled to the second memory group and includes a plurality of second page buffers. The first page buffer group performs a first data processing operation on data stored in the first page buffer group and stores a result of the first data processing operation. The second page buffer group performs a second data processing operation on data stored in the second page buffer group and stores a result of the second data processing operation. The first and second data processing operations are performed at substantially the same.
