Abstract:
1. A method for implementing a system comprising a memory device, the method comprising: (i) manufacturing a plurality of non-volatile memory cells, each comprising a phase-change material configured to change state reversibly between at least an amorphous state and a crystalline state having different electrical resistances, wherein the manufacturing comprises forming a layer comprising the phase-change material having an original amorphous state at the end of the manufacturing; (ii) pre-programming a memory device comprising the plurality of non-volatile memory cells, by electrically recrystallizing a selection of the memory cells from their original amorphous state, to obtain a pre-programmed memory device; and (iii) assembling the pre-programmed memory device in the system during which the device is subjected to a temperature of between 240° C. and 300° C.
