Semiconductor integrated circuit device, memory module, storage device and the method for repairing semiconductor integrated circuit device

A semiconductor integrated circuit device comprising, over one semiconductor substrate while sharing a data bus:

• a central processing unit;
• a nonvolatile memory which may be electrically reprogrammed and accessed by said central processing unit;
• and a volatile memory which may be accessed by said central processing unit,
• wherein said nonvolatile memory and said volatile memory individually include register means having data input terminals connected with said data bus, so that their functions are partially determined according to the information set in said register means,
• wherein said nonvolatile memory includes as plurality of nonvolatile memory cells, some of which are nonvolatile memory cells for storing initialization data, and has an operation mode for allowing the initialization data storing nonvolatile memory cells to be reprogrammed, and an operation mode for inhibiting the same, so that initialization data is read out from the nonvolatile memory cells and outputted in response to an instruction to initialize said semiconductor integrated circuit device, and
• wherein said register means latches initialization data from said nonvolatile memory in response to the instruction to initialize said semiconductor integrated circuit device.
