Abstract:
A method for identifying cell coupling in a memory system includes generating a two-dimensional pseudorandom binary sequence array. The method also includes performing an erase operation on a plurality of cells of a memory block of the memory system. The method also includes performing a write operation on the plurality of cells using the two-dimensional pseudorandom binary sequence array. The method also includes performing a read operation on the plurality of cells to identify a voltage value for each cell of the plurality of cells. The method also includes identifying cell coupling between respective cells of the plurality of cells using the voltage value for each of the cells of the plurality of cells.
