Abstract: A semiconductor device can reduce power consumption in a low power mode and includes a first input/output circuit configured to detect a first entry signal transiting at a first time and output a detection signal indicating an entry into a power saving mode according to a result of the detection. A second input/output circuit is configured to receive a second entry signal transiting at a second time earlier than the first time, and a control circuit is configured to block power supplied to the second input/output circuit in response to the detection signal indicating the entry.

Abstract: A data storage device includes a central processing unit (CPU); a peripheral device; a power management unit (PMU) configured to control a power supply to the CPU and the peripheral device; and a receiver configured to transmit a second signal to the PMU through a second transmission path after transmitting a first signal to the CPU through a first transmission path, the receiver being configured such that the first and second signals transmitted by the receiver are signals that were output from a host.

Abstract: Provided are an abrasion-detection type conveyor belt and a manufacturing method thereof. A polymer composition ratio of is set to 40-60% of styrene-butadiene rubber (SBR) and 60-40% of natural rubber (NR), and an adhesive strength between a cover rubber layer and an abrasion-detection color layer is set to 13 kN/m (33 kgf/inch). As compared to the existing product, material properties of the abrasion-detection color layer are improved to extend the available life of the abrasion detection type conveyor belt. The abrasion-detection type conveyor belt is cost-effective, simplifies a belt line, and reduces an inspection time.

Abstract: A data storage device includes a data storage medium and a controller. The controller is configured to control at least one of a reading, erasing, and writing operation on the data storage medium. The controller includes an interface and a power management unit. The interface is configured to exchange at least one of a command, an address, and data with a host. The power management unit is configured to change the power mode of the interface into a power saving mode if: a command input from the host is not executed, data transfer is not actually executed in executing the command, or status information is not reported after the command is executed.

Abstract: A method of controlling a power saving mode used in a serial advanced technology attachment (SATA) interface. The method of controlling a power saving mode used in a SATA interface for data transmission between a transmitter and a receiver includes: requesting the receiver to enter one of a plurality of power saving modes in a SATA protocol using the transmitter; and selecting one of the power saving modes using the receiver. In the method of controlling a power saving mode in a SATA interface, since a power saving mode can be selected independently of a power saving mode requested by a transmitter, a system can operate in a power saving mode that is suitable for the required properties of the system in accordance with a SATA protocol. Furthermore, the properties of the system required by a user can be realized by selecting a user-defined power saving mode.

Abstract: A cyclic redundancy check (CRC) management method performed in a serial advanced technology attachment (SATA) interface and a data storage device using the CRC management method. A host interface connected to the SATA interface performs CRC computation on transmitted data to generate a first CRC code, determines whether a host interface block error or a data integrity error occurs, or the status of a data storage device needs to be reported to the host interface, generates a second CRC code, which is different from the first CRC code, according to the determination result. If a frame including the transmitted data and the second CRC code is transmitted to a host, the host performs CRC computation on a data FIS in the transmitted data to expect the first CRC code. Since the CRC code in the transmitted data is the second CRC code, the host recognizes that the transmitted data is wrong and provides an error notification to the data storage device.
