20100268872 | DATA STORAGE SYSTEM COMPRISING MEMORY CONTROLLER AND NONVOLATILE MEMORY - A data storage system comprising a storage device comprising at least one nonvolatile memory, and a controller connected to the storage device through a channel. The memory controller sends part or all of a command, address and data for a next operation to the nonvolatile memory while the nonvolatile memory device is in a busy state. The memory controller then performs a background operation while the nonvolatile memory device remains in the busy state. | 10-21-2010 |
20100302664 | DISK DRIVE DATA STORAGE SYSTEMS AND METHODS USING BACKUP POWER SOURCE CHARGED BY SPINDLE MOTOR - A data storage system includes data storage including at least one data storage disk driven by a spindle motor and a control circuit coupled to the data storage and configured to be coupled to a main power source and a backup power source. The control circuit is configured to detect failure of the main power source, to responsively write data to the data storage while powered by the backup power source, and to subsequently recharge the backup power source using the spindle motor. The control circuit may be configured to further write data to the data storage using the recharged backup power source. The data storage system may further include a head configured to read and/or write data to or from the at least one data storage disk, and the control circuit may be configured to park the head using the recharged backup power source. | 12-02-2010 |
20140082250 | EMBEDDED MULTIMEDIA CARD (eMMC), HOST FOR CONTROLLING eMMC, AND METHOD OPERATION FOR eMMC SYSTEM - An eMMC includes flash memory including an extended card specific data (CSD) register (“EXT_CSD register”), and an eMMC controller that controls operation of the flash memory. The eMMC controller is receives a clock from a host via a clock line, receives a SEND_EXT_CSD command from the host via a command line, and provides the host with eMMC information stored in the EXT_CSD register via a data bus in response to the SEND_EXT_CSD command, the eMMC information including maximum operating frequency information for the eMMC. | 03-20-2014 |
20140082398 | EMBEDDED MULTIMEDIA CARD (eMMC), HOST CONTROLLING eMMC, AND METHOD OPERATING eMMC SYSTEM - An embedded multimedia card (eMMC) is provided. The eMMC includes a clock channel receiving a clock output from a host, data channels receiving data signals from the host, and a command channel receiving a SWITCH command including delay offset values from the host so as to adjust a delay of at least one of the data signals, which are received, in response to the delay offset values. | 03-20-2014 |

20100172380 | MODE-LOCKED LASER - The present disclosure provides in a first aspect a mode-locked laser for generating laser pulses. The mode-locked laser comprises an optical coupler and a first optical path capable of carrying optical signals from and to the optical coupler. The first optical path includes an optical amplifier that is arranged so that saturation of optical amplification causes amplitude modulation of the light. The optical amplifier has a saturation time that is shorter than a pulse transition period of the mode-locked laser and is arranged for recovery of amplifying properties after the saturation within a period of time that is shorter than the pulse transition period of the mode-locked laser. The laser further comprises a second optical path capable of carrying optical signals from and to the optical coupler. The second optical path includes an optical isolator. The first optical path has a non-linear property and is arranged so that, when a light pulse that is received from the second optical path is split by the optical coupler into component light pulses that are directed in opposite directions in the first optical path, the component light pulses experience differing shifts in phase and wherein the mode-locked laser is arranged so that mode-locked lasing is initiated by a light pulse that is amplitude modulated by the optical amplifier. | 07-08-2010 |
