Abstract
A semiconductor chip Dof a flash memory which is stacked together with other semiconductor chips D˜DN to form a multi-chip package (MCP), including a memory cell arrayof the flash memory for storing an ID code and an upper address, wherein the ID code is written into the a fuse data regionF of the memory cell arraybefore the assembly process. According to the invention, ID codes and upper addresses can be assigned and written to each of the semiconductor chips of a multi-chip package easily without increasing the size of the semiconductor chips in comparison with the prior art.
