  • Patent number: 11880569
    Abstract: A clock mode configuration circuit for a memory device. A memory system includes any number of memory devices serially connected to each other, where each memory device receives a clock signal. The clock signal can be provided either in parallel to all the memory devices or serially from memory device to memory device through a common clock input. The clock mode configuration circuit in each memory device is set to a parallel mode for receiving the parallel clock signal, and to a serial mode for receiving a source synchronous clock signal from a prior memory device. Depending on the set operating mode, the data input circuits will be configured for the corresponding data signal format, and the corresponding clock input circuits will be either enabled or disabled. The parallel mode and the serial mode is set by sensing a voltage level of a reference voltage provided to each memory device.

  • Patent number: 11664463
    Abstract: 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.

  • Patent number: 11362645
    Abstract: 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 power island of the plurality of 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.

  • Patent number: 11150808
    Abstract: A method and system for controlling an MBC configured flash memory device to store data in an SBC storage mode, or a partial MBC storage mode. In a full MBC storage mode, pages of data are programmed sequentially from a first page to an Nth page for each physical row of memory cells. Up to N virtual page addresses per row of memory cells accompany each page to be programmed for designating the virtual position of the page in the row. For SBC or partial MBC data storage, a flash memory controller issues program command(s) to the MBC memory device using less than the maximum N virtual page addresses for each row. The MBC memory device sequentially executes programming operations up to the last received virtual page address for the row.

  • Patent number: 11102809
    Abstract: In one embodiment, a method is performed by a wireless station. The method includes determining that a wireless network provides relay service. The wireless network includes an access point and one or more relay nodes. The method further includes transmitting a relay-service desirability indication to the access point. The method also includes receiving a relay-service confirmation from the access point. The wireless station is operable to transmit at a first station-transmission power level during a first time period and a second station-transmission power level during a second time period. The second station-transmission power level is a reduced station-transmission power level as compared to the first station-transmission power level. In addition, the method includes transmitting an uplink transmission at the second station-transmission power level responsive to the relay-service confirmation from the access point.

  • Patent number: 11082956
    Abstract: 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.

  • Patent number: 8819377
    Abstract: A memory system architecture is provided in which a memory controller controls memory devices in a serial interconnection configuration. The memory controller has an output port for sending memory commands and an input port for receiving memory responses for those memory commands requisitioning such responses. Each memory device includes a memory, such as, for example, NAND-type flash memory, NOR-type flash memory, random access memory and static random access memory. Each memory command is specific to the memory type of a target memory device. A data path for the memory commands and the memory responses is provided by the interconnection. A given memory command traverses memory devices in order to reach its intended memory device of the serial interconnection configuration. Upon its receipt, the intended memory device executes the given memory command and, if appropriate, sends a memory response to a next memory device. The memory response is transferred to the memory controller.
