摘要： A semiconductor memory device comprises a memory cell array comprising a plurality of memory cells, and a filling command determiner that receives a command signal and an address signal and determines whether the command signal corresponds to a filling command. Upon determining that the command signal corresponds to a filling command, the filling command determiner connects a first source voltage to a bitline and connects a second source voltage to a complementary bitline corresponding to the bitline. The bitline is connected to a selected memory cell corresponding to the address signal.

摘要： A multi-level cell (MLC) phase-change memory device divides data into data groups each comprising multiple bits of data, and stores each of the data groups in a selected phase-change memory cell. A data group is stored in a selected phase-change memory cell by applying a pulse current to the selected phase-change memory cell with a pulse current characteristic corresponding to a data value of the data group. The pulse current characteristic can comprise, for instance, a magnitude, downward slope, or duration of the pulse current. Data is read from a selected phase-change memory cell by sensing a voltage of a bitline connected to the selected phase-change memory cell and comparing the sensed voltage simultaneously with a plurality of reference voltages.
