    Abstract: An input buffer for processing an external signal is provided in one of passways, which is the most closest to a line for equally dividing the whole of a plurality of memory cell blocks longitudinally or laterally into two sections, the passway interposing between the adjacent memory cell blocks of the plurality of memory cell blocks to which a processed signal of the input buffer is transmitted, whereby the length of the signal pass from the input buffer to each memory cell of the memory cell blocks can be shortened. Therefore, since the memory cell or a logic element existing between the input buffer and the memory cell is operated by a pulse of little distortion without delay of time, a access time can be reduced and a processing speed of a microprocessor can be increased. Further, a degree of freedom in designing a system of a memory or the microprocessor is further improved.

    Abstract: Manufacturing processes for phase change memory have suffered from the problem of chalcogenide material being susceptible to delamination, since this material exhibits low adhesion to high melting point metals and silicon oxide films. Furthermore, chalcogenide material has low thermal stability and hence tends to sublime during the manufacturing process of phase change memory. According to the present invention, conductive or insulative adhesive layers are formed over and under the chalcogenide material layer to enhance its delamination strength. Further, a protective film made up of a nitride film is formed on the sidewalls of the chalcogenide material layer to prevent sublimation of the chalcogenide material layer.

    Abstract: Memory cells in which an erase and write operation is performed by injecting electrons from a substrate and extracting the electrons into a gate electrode constitute a semiconductor nonvolatile memory device. That is a gate extraction semiconductor nonvolatile memory device. In that device, if an erase bias is applied in a first process of an erase and write operation, memory cells in an overerase condition occur and the charge retention characteristics of such memory cells are degraded. The present invention provides a semiconductor nonvolatile memory device using means for writing all the memory cells in an erase unit before applying the erase bias, and then applying the erase bias.
