Method for writing data, memory device and data writing system

A memory device which memorizes data comprising:

• an identification information memorizing part that stores an identification information assigned to said memory device;
• a nonvolatile memory;
• a writing circuit configured to write data in said nonvolatile memory;
• a buffer configured to store said writing object data temporarily;
• a receiving part configured to receive a combination data which is obtained by associating and combining identification information with respect to a plurality of memory devices and writing object data, and a writing signal which indicates writing of data into said nonvolatile memory;
• and
• a comparing part configured to compare said identification information memorized in said identification information memorizing part and identification information with respect to said plurality of memory devices included in said combination data;
• wherein
• said comparing part extracts writing object data corresponding to said memory device from said combination data on the basis of a result of the comparison,
• said buffer stores temporarily said writing object data extracted by said comparing part,
• said writing circuit writes said writing object data which is read out from said buffer into said nonvolatile memory in response to said writing signal.

A data writing system constituted by a plurality of memory devices and a writing device which writes data into said plurality of memory devices wherein

• said writing device includes:
• data maintaining means for maintaining writing object data corresponding to each of said plurality of memory devices;
• obtaining means for obtaining identification information assigned to each of said plurality of memory devices from said plurality of memory devices;
• generating means for generating combination data by associating and combining said identification information and said writing object data with respect to said plurality of memory devices;
• and
• sending means for sending said combination data to said plurality of memory devices,
• each of said plurality of memory devices includes:
• receiving means for receiving said combination data;
• extracting means for extracting said writing object data corresponding to the memory device on the basis of said identification information from said combination data;
• and
• memorizing means for memorizing said target data for writing extracted from said combination data.
