Abstract: An information processing apparatus includes: a solid state drive (SSD) configured with a multi-bit cell for storing multi-bit data in one memory cell and configured to include an electrically rewritable non-volatile storage unit; and a main control unit configured to execute processing based on data stored in the SSD. The SSD includes a storage control unit, which is a storage control unit configured to control access to the non-volatile storage unit, and configured to execute a storage process through which a variation width of a threshold voltage is changeable when the multi-bit data is stored in the multi-bit cell.

Abstract: A computer implemented method and system includes receiving a tamper notification responsive to improper opening of a device enclosure, starting a delay time timer in response to receiving the tamper signal, initiating saving of volatile memory data in a storage device to non-volatile storage, providing a power down notification signal to a device power controller in response to the timer reaching a predetermined state, and powering down the device in response to the power down notification signal.

Abstract: An information processing apparatus includes: a processor; a controller; a solid-state storage device; and a heat dissipation fan. The processor and the controller are connected with the solid-state storage device by using a bus, and the solid-state storage device is installed at a position corresponding to the heat dissipation fan. The processor acquires identification information of the solid-state storage device in association with location information indicating the position of the solid-state storage device, and the controller acquires identification information and a logical address of the solid-state storage device in advance, configures a reference table by associating location information corresponding to an identification number with a logical address corresponding to the identification information.

Abstract: An information processing apparatus includes a first processor that executes a hardware startup process, a second processor separate from the first processor, and a memory interface which includes a temperature sensor, the memory interface being configured to interface with a memory, wherein the memory interface is configured to, when a temperature sensed by the temperature sensor reaches a predetermined temperature threshold value, throttle performance of the memory, the first processor executing the hardware startup process includes transmitting a plurality of temperature threshold values to the memory interface via a first interface, and the second processor, in response to an event, transmits selection information to the memory interface via a second interface different from the first interface, the selection information indicating selection of one of the plurality of temperature threshold values to be set as the predetermined temperature threshold value.

Abstract: A method of manufacturing an information processing apparatus includes storing, in a first storage area of a solid-state drive (SSD) of the information processing apparatus, an installation program which when executed causes the information processing apparatus to install preload data, executing the installation program to install the preload data at least partially in a second storage area of the SSD, and after executing the installation program, moving portions of the preload data stored in the second storage area to the first storage area of the SSD. The first storage area is configured to store single bit cells in which one bit of data is stored in one memory cell, and the second storage is configured to store multi-bit cells in which multiple bits of data are stored in one memory cell.
