摘要:
Read disturbs in phase change memories may be reduced by progressively reducing the read pulse falling edges. This may reduce the possibility of quenching and inadvertent amorphization of at least a portion of the bit. As a result, in some embodiments, read disturbs may be reduced.

An information handling system includes a buck converter, having a synchronous switch, to supply power to an electrical load. A first inductor is placed in series with the synchronous switch, and a second inductor is inductively coupled to the first inductor. A switched path recovers energy stored in the first inductor, via the second inductor, when the synchronous switch is open.

A memory device is operable in either a high mode or a low speed mode. In either mode 32 bits of data from each of two memory arrays are prefetched into respective sets of 32 flip-flops. In the high-speed mode, the prefetched data bits are transferred in parallel to 4 parallel-to-serial converters, which transform the parallel data bits to a burst of 8 serial data bits and apply the burst to a respective one of 4 data bus terminals. In the low speed mode, two sets of prefetched data bits are transferred in parallel to 8 parallel-to-serial converters, which transform the parallel data bits to a burst of 8 serial data bits and apply the burst to a respective one of 8 data bus terminals.

A memory system couples command, address or write data signals from a memory controller to a memory device and read data signals from the memory device to the memory controller. A respective strobe generator circuit in each of the memory controller and the memory device each generates an in-phase strobe signal and a quadrature strobe signal. Command, address or write data signals stored in respective output latches in the memory controller are clocked by the in-phase signals from the internal strobe generator circuit. These command, address or write data signals are latched into input latches in the memory device by the quadrature strobe signal coupled from the memory controller to the memory device. In substantially the same manner, read data signals are coupled from the memory device to the memory controller using the in-phase and quadrature strobe signals generated by the internal strobe generator circuit.

A method of managing access to a healthcare information system of a healthcare establishment communications network. The method comprises receiving data regarding a wirelessly detectable tag associated with a clinician; determining whether the clinician is positioned relative to a terminal of the healthcare establishment communications network such that a proximity condition is satisfied based at least in part on the data regarding the wirelessly detectable tag; responsive to the proximity condition being satisfied, providing an opportunity for authentication of the clinician; and responsive to successful authentication of the clinician, establishing a session for the clinician between the terminal and the healthcare information system. The ability to detect proximity of clinician facilitates the process by which the clinician may access the healthcare information system, while the requirement for authentication of the clinician minimizes the risk of data being made available to an unauthorized party.

A structure for supporting an instrument panel by a defroster nozzle so that sufficient rigidity can be imparted to the top of the instrument panel. A supporting member is attached to an upper wall of the defroster nozzle arranged inside the instrument panel and is disposed in contact with the instrument panel to support same.
摘要:
A method and system for generating a reference voltage for memory device signal receivers operates in either a calibration mode or a normal operating mode. In the calibration mode, the magnitude of the reference voltage is incrementally varied, and a digital signal pattern is coupled to the receiver at each reference voltage. An output of the receiver is analyzed to determine if the receiver can accurately pass the signal pattern at each reference voltage level. A range of reference voltages that allow the receiver to accurately pass the signal pattern is recorded, and a final reference voltage is calculated at the approximate midpoint of the range. This final reference voltage is applied to the receiver during normal operation.
