摘要： A non-volatile memory device using existing row decoding circuitry to selectively provide a global erase voltage to at least one selected memory block in order to facilitate erasing of all the non-volatile memory cells of the at least one selected memory block. More specifically, the erase voltage is coupled to the cell body or substrate of memory cells of the at least one selected memory block, where the cell body is electrically isolated from the cell body of non-volatile memory cells in at least one other memory block. By integrating the erase voltage path with the existing row decoding circuitry used to drive row signals for a selected memory block, no additional decoding logic or circuitry is required for providing the erase voltage to the at least one selected memory block.

摘要： In one embodiment, a method is performed by a base station in a wireless network. The method includes receiving from a user device a request to reconfigure already-active uplink semi-persistent scheduling (SPS). The already-active uplink SPS grants the user device a resource block allocation (RBA) and a modulation and coding scheme (MCS) for periodic uplink transmissions. The already-active uplink SPS includes a time-interval parameter, the time-interval parameter specifying a time interval between the periodic uplink transmissions. The request includes information related to a proposed adjustment of the time-interval parameter. The method further includes reconfiguring the already-active uplink SPS. The reconfiguring includes modifying the time-interval parameter based, at least in part, on the information.

摘要： A memory device includes core memory such as flash memory for storing data. The memory device includes a first power input to receive a first voltage used to power the flash memory. Additionally, the memory device includes a second power input to receive a second voltage. The memory device includes power management circuitry configured to receive the second voltage and derive one or more internal voltages. The power management circuitry supplies or conveys the internal voltages to the flash memory. The different internal voltages generated by the power management circuitry (e.g., voltage converter circuit) and supplied to the core memory enable operations such as read/program/erase with respect to cells in the core memory.

摘要： A method includes receiving an Orthogonal Frequency Division Multiplexing (OFDM) signal comprising a plurality of Doppler-shifted OFDM subcarriers and determining frequency-shift data corresponding to the plurality of Doppler-shifted OFDM subcarriers. The determining includes calculating frequency-shift data for each Doppler-shifted OFDM subcarrier of the plurality of Doppler-shifted OFDM subcarriers, thereby yielding a plurality of subcarrier-specific frequency-shift values and calculating an average of the plurality of subcarrier-specific frequency-shift values. The method further includes frequency shifting each subcarrier of the plurality of Doppler-shifted OFDM subcarriers by a value based on the determined frequency-shift data multiplied by a frequency index of each subcarrier.

摘要： Disclosed is a method of manufacturing flash memory with a vertical cell stack structure. The method includes forming source lines in a cell area of a substrate having an ion-implanted well and forming an alignment mark relative to the source lines. The alignment mark is formed in the substrate outside the cell area of the substrate. After formation of the source lines, cell stacking layers are formed. After forming the cell stacking layers, cell pillars in the cell stacking layers are formed at locations relative to the previously formed source lines using the alignment mark to correctly locate the cell pillars.

摘要： Systems and methods manage power in an integrated circuit using power islands. The integrated circuit includes a plurality of power islands wherein a power consumption of each power island within the plurality of power islands is independently controlled within each of the power islands. A power manager determines a target power level for one power island of the plurality of power islands. The power manager then determines an action to change a consumption power level of the one power island of the plurality of power islands to the target power level. The power manager performs the action to change the consumption power level of the one power island of the plurality of power islands to the target power level.
