Abstract
A flash memory device including memory cells, each memory cell configured to store bits, a sensing circuit configured to sequentially sense, for each memory cell, sets of the bits of the memory cell, a data rearrangement unit configured to receive words of data and to rearrange bits of the words to be stored in the memory cells, and an output circuit configured to output a group of the words using the sets of bits from one sensing, at least as early as during a subsequent sensing of sets of bits.
Claims6
A method of reading a semiconductor memory device comprising:
- sensing a plurality of first sets of bits stored in a plurality of multi level memory cells, each multi level memory cell having a plurality of sets of bits, each set to be sensed sequentially, the first sets of the bits to be sensed in a first sensing of the multi level memory cells;
- and
- outputting words of data using the first sets of bits at least as early as during a subsequent sensing of a plurality of subsequent sets of bits of the multi level memory cells.
