Recording medium control element, recording medium control circuit board, and recording medium control device

A recording medium control circuit board, comprising:

• a first input/output module configured to input/output a command and data to/from a host device;
• a second input/output module configured to input/output a command and data to/from a recording medium;
• a first control module configured to control the input/output of the command and data performed by the second input/output module based on the command and data input/output to/from the first input/output module;
• a buffer holding the data input/output to/from the first and second input/output modules;
• a second control module configured to control writing and reading data to/from the buffer;
• a clock generating module configured to generate a first clock signal and a second clock signal whose frequency is lower than a maximum operating frequency of the recording medium;
• and
• a signal supply module configured to supply the first clock signal to the recording medium and the first and second input/output modules, and supplying the second clock signal to the first and second control modules.
