摘要： A method to test the erase condition of memory cells in a memory array device is achieved. The method is further extended to methods to detect and correct under erase and over erase conditions. The erase condition of a section of the memory array device is altered to form an erased section and non-erased sections. The control gates of the memory cells in the non-erased sections are forced to a normal off-state voltage sufficient to turn off erased cells. The control gates of the memory cells in non-selected subsections of the erased section are forced to a guaranteed off-state voltage that will turn off erased cells including those that are over erased. The control gates of the memory cells in a selected subsection of the erased section are forced to a check voltage. Thereafter, the bitline current of the selected subsection of the erased section is measured to determine erase condition of the selected subsection of the erase section.

摘要： A system includes a signal processing module and a control module. The signal processing module receives a first clear channel assessment (CCA) signal for a first sub-channel of a communication channel, increases a pulse width of the first CCA signal by a predetermined period of time, and generates a second CCA signal.

摘要： A process for the preparation of new polyols and polyesters from a natural oil or other unsaturated fatty acid esters is described. The process involves ozone cleavage of double bonds in the fatty acid chains of the oils along with coupling of a hydroxylated compound such as a mono-alcohol, a diol, or a polyol to the cleaved ends of the molecules resulting from the cleavage with a base. The resulting polyols and polyesters are as intermediates for polymers.

摘要： A low power E-fuse repair methodology substantially removes system latency during memory and/or E-fuse farm module power-down in a device that employs E-fuse farm technology. The method maintains power to the repair registers and minimal control logic in the memories, while all other circuitry can be either placed in a low power data retention mode, or completely powered off. There is no need to rescan the repair data from the E-fuse farm after one or more memories are powered back up. This provides dynamic power savings since there is no longer any need to idle the system to reload repair data. Since the E-fuse farm can be powered down after initial system power-up and repair data is loaded into the memories, there is also a significant leakage power savings.
摘要翻译：在采用电熔丝农场技术的设备中，低功率电熔丝修复方法可显着消除存储器和/或E-fuse农场模块断电期间的系统延迟。该方法维持修复寄存器的电源和存储器中的最小控制逻辑，而所有其他电路可以放置在低功率数据保持模式或完全断电。一个或多个存储器上电后，不需要重新扫描电源保险丝座的修复数据。这样可以节省动力，因为不再需要空闲系统来重新加载修复数据。由于电源熔断器场在初始系统上电后可以关闭电源，并将数据修复到存储器中，所以还可以节省大量的泄漏功率。

摘要： A wireless network device having active and inactive modes comprises a clock generating module that generates a first clock signal having a first clock rate. A voltage supply module generates a first voltage level and a second voltage level that is less than the first voltage level. A first digital module receives the first clock rate and the first voltage level during the active mode, receives the second voltage level during the inactive mode and does not receive the first clock signal during the inactive mode. A first analog module communicates with the voltage supply module and has reduced current consumption during the inactive mode.
