Non-volatile memory module for preventing system failure and system including the same

A non-volatile memory system comprising

• a first socket and a second socket each having a notch coupler;
• a first memory module configured to comprise a plurality of non-volatile memory devices and to store system software;
• a memory controller configured to control the first memory module;
• and
• a printed circuit board on which the memory controller and the first and second sockets are installed and electrical signals lines are formed between the memory controller and the first and second sockets,
• wherein the first memory module can be installed at the first socket but cannot be installed at the second socket;
• and
• an alarm unit configured to generate an alarm sound when the first memory module is removed from the first socket.

A system including a non-volatile memory system, comprising:

• a first socket and a second socket each having a notch coupler;
• a first memory module configured to comprise a plurality of non-volatile memory devices and to store system software;
• a memory controller configured to control the first memory module;
• a printed circuit board on which the memory controller and the first and second sockets are installed and electrical signals lines are formed between the memory controller and the first and second sockets,
• wherein the first memory module can be installed at the first socket but cannot be installed at the second socket;
• and
• wherein the notch coupler in the first socket is different from the notch coupler in the second socket.

A non-volatile memory module for system software, comprising:

• a memory module substrate in which at least one notch and a plurality of input/output pins are formed;
• a first non-volatile memory device installed on at least one side of the memory module substrate to store a system boot code;
• a second non-volatile memory device storing the system software,
• wherein the non-volatile memory module can be installed at a socket comprising a notch coupler that can be engaged with the at least one notch but cannot be installed at a socket used for a non-volatile memory module for a memory capacity extension, which comprises a notch different from the at least one notch;
• and
• an alarm unit configured to generate an alarm sound when the non-volatile memory module is removed from the socket comprising the notch coupler.
