First main and second hydraulic pressure paths, master cut valves configured to open and close the first and second main hydraulic pressure paths, respectively, a slave cylinder that operates in accordance with an operation amount of a brake operator, a first communication path that communicates from the slave cylinder to the first main hydraulic pressure path, and a second communication path that communicates from the slave cylinder to the second main hydraulic pressure path are provided. The slave cylinder includes a single hydraulic pressure chamber. The slave cylinder communicates with the first and second communication paths through a common flow path connected to the hydraulic pressure chamber. The slave cylinder is configured to be able to increase a pressure on a downstream side of the first or second main hydraulic pressure path. An on-off valve is provided in at least one of the first and second communication paths.

A dynamic access random access card is provided with a dynamic random access memory and a source for generating a plurality of reference clock pulses. A control circuit generates refresh operations of the dynamic access memory in response to the plurality of reference clock pulses generated by the source, the initiation of the refresh operations being independent of any external refresh request. The refresh operations are interrupted and the dynamic random access memory is set to a standby condition upon detection of a predetermined external signal, thereby permitting read/write operations of the dynamic random access memory.
