Abstract:
1. A method for preparing a non-volatile memory chip package, including preparing the non-volatile memory chip package for surface mounting to a substrate in a surface mounting process which heats the non-volatile memory chip package, the non-volatile memory chip package comprises a die comprising a plurality of blocks of non-volatile storage elements, the method comprising: preloading a block of the plurality of blocks with data; identifying a block of the plurality of blocks which is not preloaded with data, the block which is not preloaded with data is in an erased state; responsive to the identifying, raising threshold voltages of non-volatile storage elements of the block which is not preloaded with data, from an initial level which is a level of the erased state, to higher levels; and following the surface mounting process, erasing the non-volatile storage elements of the block which is not preloaded with data to the erase state.
