Abstract
Data is programmed in a respective block of non-volatile three dimensional memory. The block contains a plurality of rows of subblocks, each row having S subblocks. Programming data in the respective block includes successively programming data in individual rows of the respective block. Programming data in each row is completed prior to programming data in a next row. Programming data in a row includes successively programming data in individual subblocks of the row, in a predefined order. The programming of data in each subblock is completed prior to programming data in a next subblock. While programming data in each individual subblock, a number of XOR signatures, sufficient in number to enable recovery from a short circuit that disables two or three word lines, are generated in volatile memory, and then copied to non-volatile memory prior to programming data in a next subblock in the respective block.
