Abstract:
1. A method of accessing a nonvolatile semiconductor memory device including a nonvolatile memory cell array having first and second pages, the nonvolatile semiconductor memory device further including a latch circuit coupled to the memory cell array, the method comprising; supplying a first command and a first address for a first page to cause transfer of data stored in the first page to the latch circuit; reading the transferred data out of the latch circuit while supplying a toggling read enable signal to the nonvolatile semiconductor memory device; supplying a superseding data to the nonvolatile semiconductor memory device to change a portion of the transferred data in the latch circuit while allowing the other portion of the transferred data to stay unchanged in the latch circuit; and supplying a second command to initiate programming into the second page according to the superseding data and other portions of the transferred data in the latch circuit.
