1. A memory system, comprising:
- a memory device storing data;
a memory controller receiving a request from a host, controlling the memory device according to the request, and communicating between the memory device and the host, the memory device comprising;
an enable signal generation unit generating an enable signal in response to a command output from the memory controller;
a fix code storage unit storing product information of the memory device, wherein the product information is not varied;
a logic code generation unit generating variable information of the memory device; and
an output unit combining the product information from the fix code storage unit with the variable information from the logic code generation unit and outputting the combined information in response to the enable signal,wherein the enable signal generation unit, the fix code storage unit, the logic code generation unit and the output unit are included in a control logic which receives the command from the memory controller and operates the memory device, the output unit being operated in response to a single internal clock used in the control logic for operating the memory device, andwherein the output unit outputs the combined information using the single internal clock.

10. A memory device, which stores data and is controlled by a memory controller communicating between the memory device and a host, comprising:
-
a plurality of memory blocks storing data; a peripheral circuit performing at least one of a program operation, a read operation and an erase operation on the plurality of memory blocks; and a control logic controlling the peripheral circuit, wherein the control logic combines product information, which is not varied, of the memory device with variable information of the memory device in response to a command output from the memory controller, and outputs combined information including the product information and the variable information to the memory controller in response to a single internal clock that is used in the control logic for operating the memory device. - View Dependent Claims (11, 12, 13, 14, 15)
