Abstract
An information processing device includes a first processor core of 2n-bits unit, a second processor core of n-bit(s) unit, a DRAM set including a first DRAM and a second DRAM of n-bit(s) unit, a first transmitting path between the first processor core and the DRAM set, a second transmitting path between the second processor core and the first or second DRAM, a transmitting path switching circuit, and a power supply controlling circuit. In normal operation, with switching to the first transmitting path and supplying power to the first processor core and the first and second DRAMs, the first processor core uses the first and second DRAMs. In power saving operation, with switching to the second transmitting path, supplying power to the second processor core and the first DRAM and stopping power to the first processor core and the second DRAM, the second processor core uses the first DRAM.
