PROBLEM TO BE SOLVED: To enable a log memory access circuit to perform both of switching of a log gathering apparatus for gathering a log and power supply to each part of the circuit. SOLUTION: The log memory access circuit includes: a log memory for storing logs; a connection system switching part for switching a first connection system connecting a first access device for accessing the log memory to the log memory and a second connection system connecting a second access device for accessing the log memory to the log memory; a switching input part for inputting a switching instruction; a switching instruction part for instructing the connection system switching part to switch between the first connection system and the second connection system on the basis of the input switching instruction; a first power supply part for supplying power from the first access device to each of parts; and a second power supply part for supplying power from the second access device to each of parts when the power supply of the first power supply part is off.
