20120075930 | REUSE OF INFORMATION FROM MEMORY READ OPERATIONS - A nominal reference read operation compares analog voltages of the memory cells to at least one nominal reference voltage. A shifted reference read operation compares the analog voltages of the memory cells to at least one shifted reference voltage that is shifted from the nominal reference voltage to compensate for an expected change in the analog voltages of the memory cells. Data stored in the memory cells is decoded by a first decoding process that uses the information from either the nominal reference read operation or the shifted reference read operation.

20120075931 | Techniques for the Fast Settling of Word Lines in NAND Flash Memory - In non-volatile memory devices, a write operation typically consists of an alternating set of pulse and verify operations. After a pulse is applied, the device must be biased properly for an accurate verify, with a selected word-line settled at the desired voltage level. The techniques described here address the problem of a relatively large waiting time at the start of a verify phase of a write operation when the selected word line is moving to its first verify level, while at the same time the non-selected word lines of a NAND type array are ramping up to a read pass level. For the non-selected word lines, during the program pulse, these are set at a first voltage above ground and then, during the verify operation, then are set at the read pass level. Rather than take the non-selected word lines to ground in between, they are instead moved directly from their voltage in the pulse phase directly into their read pass level. This helps to reduce the amount of movement in the selected word line due to capacitive coupling, allowing the preparation of the verify level of a selected word line settings earlier. | 2012-03-29 |
20120075932 | CHARGE LOSS COMPENSATION DURING PROGRAMMING OF A MEMORY DEVICE - In programming a selected word line of memory cells, a first program verify or read operation is performed, after one page of a selected word line is programmed, in order to determine a first quantity of memory cells that have been programmed to a predetermined reference point in the programmed first page distribution. Prior to programming the second page of the selected word line, a second program verify or read operation is performed to determine a second quantity of cells that are still at the reference point. The difference between the first and second quantities is an indication of the quantity of cells that experienced quick charge loss. The difference is used to determine an adjustment voltage for the second page verification operation after programming of the second page. | 2012-03-29 |

20120076026 | ASYMMETRICAL LINK CONFIGURATION FOR INCREASED TOTAL NETWORK CAPACITY - A method for managing transmission settings in a wireless point-to-point link, including making a first estimate of a current required traffic capacity for transmitting in a first direction, from a first point in the wireless point-to-point link to a second point, and selecting a first technique for transmitting in the first direction, based, at least in part, on the first estimate of the current required traffic capacity, in which the first technique selected provides a traffic capacity which is less than a maximum capacity possible in the first direction. Related apparatus and methods are also described. | 2012-03-29 |
20120076027 | FEMTO-RELAY SYSTEMS AND METHODS OF MANAGING SAME - The various embodiments of the present invention relate generally to femto-relay systems and methods. An exemplary embodiment of the present invention provides a femto-relay system comprising a relay-radio, a femto-radio, a joint femto-relay resource management module, and an IP-backhaul QoS monitoring module. The relay-radio is in communication with a macro-cell base-station. The femto-radio is in communication with the relay-radio and configured to route signals between a core network and at least one femto-cell user equipment through an IP-backhaul link. The joint femto-relay resource management module is configured to intelligently manage radio resources between the femto-radio and the relay-radio to reduce cross-tier interference. The IP-backhaul QoS monitoring module is configured to monitor a QoS being delivered by the IP-backhaul link and notify the relay-radio to route signals between the femto-cell user equipment and core network through the macro-cell base-station if the QoS fall below a predetermined threshold. | 2012-03-29 |
20120076028 | Method and apparatus for performing effective feedback in wireless communication system supporting multiple antennas - A method for transmitting channel status information (CSI) of downlink multi-carrier transmission includes generating the CSI including at least one of a rank indicator (RI), a first precoding matrix index (PMI), a second PMI and a channel quality indicator (CQI) for one or more downlink carriers, the CQI being calculated based on precoding information determined by a combination of the first and second PMIs, determining, when two or more CSIs collide with one another in one uplink subframe of one uplink carrier, a CSI to be transmitted on the basis of priority, and transmitting the determined CSI over a uplink channel. If a CSI including an RI or a wideband first PMI collides with a CSI including a wideband CQI or a subband CQI, the CSI including a wideband CQI or a subband CQI has low priority and is dropped. | 2012-03-29 |
