PURPOSE: A full electronic switch control board is provided to improve the access processing speed when accessing SDRAM and to simplify the system configuration by using a processor unit equipped with a matching unit. CONSTITUTION: When a processor (100) outputs a control signal and a chip selection signal according to the order from a user, a matching unit (110) matches and transmits the signals to be processed at a proper speed in an SDRAM (200). And then, the SDRAM (200) transmits data corresponding to the signal. In addition, the SDRAM (200) receives output data from an upper block, and processes operations corresponding to the upper block. The processor (100) equipped with the matching unit (110) is capable of processing the control signal and the chip selection signal in the SDRAM (200) directly because the processor (100) does not use a buffer and a PLD (Programmable Logic Device). Therefore, by using the processor including the matching unit (110), an access time from the processor (100) to the SDRAM (200) can be reduced and a system can be simplified.
