    • A nonvolatile memory apparatus includes a separate controller circuit and memory circuit. The controller circuit is fabricated on a first integrated circuit chip. The controller circuit includes a plurality of charge pump circuits, a system interface logic circuit, a memory control logic circuit, and one or more analog circuits. The memory circuit is fabricated on a second integrated circuit chip and includes a column decoder, a row decoder, a control register, and a data register. A memory-controller interface area includes a first plurality of die bond pads on the first integrated circuit chip and a second plurality of die bond pads on the second integrated circuit chip such that the first and second integrated circuit chips may be die-bonded together. A single controller circuit may interface with a plurality of memory circuits, thus further reducing overall costs as each memory circuit does not require a dedicated controller circuit.

    • A page buffer for a NAND memory array has a data register and a cache register that are suitably organized and operated to eliminate gaps and discontinuities in the output data during a continuous page read. The cache register may be organized in two portions, and the page data in the cache may be output from the cache portions in alternation. ECC delay may be eliminated from the output by performing the ECC computation on one cache portion while the other is being output. The data register may also be organized in two portions corresponding to the cache portions, so that data may be transferred to one cache portion while the other is being output. In a variation, the continuous page read may be done without ECC.
    • 用于NAND存储器阵列的页缓冲器具有适当地组织和操作的数据寄存器和高速缓存寄存器,以在连续页读取期间消除输出数据中的间隙和不连续性。 高速缓存寄存器可以以两部分组织,并且高速缓存中的页面数据可以从高速缓存部分交替地输出。 可以通过在一个高速缓存部分执行ECC计算而另一个缓存部分被输出来从输出消除ECC延迟。 数据寄存器也可以被组织在与高速缓存部分对应的两部分中,从而数据可以被传送到一个高速缓存部分而另一个被输出。 在一个变型中,连续页面读取可以在不进行ECC的情况下完成。

    • Methods, devices, and machine readable media are provided for transmission in a network with active and sleeping clients. Some examples can include transmitting a first multicast stream of data in response to an active wireless client being associated with the wireless network device at a particular time. The method can include transmitting a second multicast stream of the data after the first multicast stream in response to a sleeping wireless client being associated with the wireless network device at the particular time and in response to a delivery traffic indication message count expiring. The first and/or second multicast streams of the data can be retransmitted a number of times (e.g., at different data rates). An active/sleep status can be maintained for the wireless clients. A unicast stream can be transmitted when the number of clients does not exceed a threshold.

    • A memory system includes an array of solidstate memory devices which are in communication with and under the control of a controller module via a device bus with very few lines. This forms an integrated-circuit mass storage system which is contemplated to replace a mass storage system such as a disk drive memory in a computer system. Command, address and data information are serialized into component strings and multiplexed before being transferred between the controller module and the array of memory devices. The serialized information are is accompanied by a control signal to help sort out the multiplexed components. Each memory device in the array is mounted on a multi-bit mount and assigned an array address by it an array mount. An A memory device is selected by an appropriate address broadcast over the device bus, without requiring the usual dedicated select signal. A reserved array particular mount multi-bit configuration is used to unconditionally select the device mounted thereon. A reserved predefined address broadcast over the device bus deselects all previously selected memory devices. Read performance is enhanced by a read streaming technique in which while a current chunk of data is being serialized and shifted out of the memory subsystem devices to the controller module, the controller module is also setting up the address for the next chunk of data to begin to address the memory system.
    • 存储器系统包括固态存储器件的阵列,其经由具有极少行的器件总线与控制器模块通信并处于控制器模块的控制之下。 这形成了集成电路大容量存储系统,其被设想来替代大容量存储系统,例如计算机系统中的磁盘驱动器存储器。 命令,地址和数据信息被串行化为组件字符串,并在控制器模块和存储器件阵列之间传输之前被多路复用。 串行化信息伴随着一个控制信号,以帮助整理复用的组件。 阵列中的每个存储器件都安装在多位安装上,并通过阵列安装分配阵列地址。 通过在设备总线上广播的适当地址来选择存储器件,而不需要通常的专用选择信号。 使用保留阵列特定安装多位配置来无条件地选择安装在其上的装置。 通过设备总线广播的保留的预定义地址取消选择所有先前选择的存储设备。 读取性能通过读取流技术得到增强,其中当当前块的数据被序列化并从存储器子系统设备移出到控制器模块时,控制器模块还设置下一个数据块开始的地址 寻址内存系统。
