Abstract
A USB memory includes: a USB terminal unit, a main unit which incorporates therein a NAND memory and a processor module; and a rotation portion which changes a relative position between the main unit and the USB terminal unit. The processor module switches an access management mode to a first access management mode or a second access management mode depending on the relative position between the main unit and the USB terminal unit. The processor module manages data stored in the NAND memory such that data having been stored under the first access management mode is rendered inaccessible to the host device with the second access management mode and that data having been stored under the second access management mode is rendered inaccessible to the host device with the first access management mode.
