Abstract:
A non-volatile memory device has a memory array comprising a plurality of memory cells. The array can operate in either a multilevel cell or single level cell mode and each cell has a lower page and an upper page of data. The memory device has a data latch for storing flag data and a cache latch coupled to the data latch. A read method comprises initiating a lower page read of a memory cell and reading, from the data latch, flag data that indicates whether a lower page read operation is necessary.
