<P>PROBLEM TO BE SOLVED: To provide a memory control device. <P>SOLUTION: The memory control device performs control so that a first controller and a second controller access a flash memory. A bus switch is connected to the first controller, the second controller, and the flash memory through a first, second, and third serial peripheral equipment interface buses respectively. A selection unit causes the third serial peripheral equipment interface bus to be selectively connected to any one of the first serial peripheral equipment interface bus and the second serial peripheral equipment interface bus. When the bus switch receives a first access request from the first controller through the first serial peripheral equipment interface bus, the selection unit causes the third serial peripheral equipment interface bus to be connected to the first serial peripheral equipment interface bus. <P>COPYRIGHT: (C)2013,JPO&INPIT |
