20090154286 | N-BIT SHIFT REGISTER CONTROLLER - A column repair circuit uses a system of circuits that automatically stops the shifting of register contents independently of the number of bits to be shifted. The circuit is only dependent on the number of bits in a column address repair block. By adding shift register positions to one end of each shift register chain, a dedicated block of bits is used to detect the end of the shift chain without explicitly knowing the length of the chain. The shift register positions provide a hard-programmed code that can be used to stop the shifting of data automatically. The shift register positions also provide a space for hard-programmed code bits that can be examined to determine when the shift process ends. A shift chain can be controlled with a controller so long as the information is organized into groups of ‘k’ bits. The controller only requires information regarding the value of the number ‘k’ and the pre-programmed stop code in order to control any number of bits in a shift chain. | 2009-06-18 |

20090154385 | Dynamic Adjustment of Setup Time Based on Paging Performance - Techniques for dynamically determining a target setup time based on paging performance are described. A UE in an idle mode may be assigned paging occasions, which are specific time intervals in which the UE might receive paging messages. The UE may wake up a setup time prior to each paging occasion, perform setup tasks, detect for a paging indicator, and possibly receive a paging message. The UE may dynamically determine a target setup time for each awake interval based on paging performance. The target setup time may be (i) decreased by a down step if the paging performance is better than a first threshold or (ii) increased by an up step if the paging performance is worse than a second threshold. The target setup time may be updated in each fixed update period or whenever the paging performance is outside the first and second thresholds. | 2009-06-18 |
