Abstract:
A non-volatile memory device having a memory array organized into a plurality of memory blocks, having either planar memory cells or stacks of cells. Row decoding circuitry of the memory device is configured to select a group of the plurality of memory blocks in response to a first row address, and to select a memory block of the group for receiving row signals in response to a second row address. Row decoding circuitry associated with each group of memory blocks can have a row pitch spacing that is greater than a row pitch spacing of a single memory block and less than or equal to a total row pitch spacing corresponding to the group of memory blocks.

The U-shaped flash cell string comprises one portion parallel to a surface of the substrate, comprising a junctionless bottom pass transistor, and two portions perpendicular to the surface of the substrate that comprise a string select transistor at a first top of the cell string, a ground select transistor at a second top of the cell string, a string select transistor drain, and a ground select transistor source.
Abstract:
A technique for serially coupling devices in a daisy chain cascading arrangement. Devices are coupled in a daisy chain cascade arrangement such that outputs of a first device are coupled to inputs of a second device later in the daisy chain to accommodate the transfer of information, such as data, address and command information, and control signals to the second device from the first device. The devices coupled in the daisy chain comprise a serial input (SI) and a serial output (SO). Information is input to a device via the SI. The information is output from the device via the SO. The SO of an earlier device in the daisy chain cascade is coupled to the SI of a device later in the daisy chain cascade. Information input to the earlier device via the device's SI is passed through the device and output from the device via the device's SO. The information is then transferred to the later device's SI via the connection from the earlier device's SO and the later device's SI.

Abstract:
A multi-chip package has a substrate with electrical contacts for connection to an external device. A CPU die is disposed on the substrate and is in communication with the substrate. The CPU die has a plurality of processor cores occupying a first area of the CPU die, and an SRAM cache occupying a second area of the CPU die. A DRAM cache is disposed on the CPU die and is in communication with the CPU die. The DRAM cache has a plurality of stacked DRAM die. The plurality of stacked DRAM dies are substantially aligned with the second area of the CPU die, and substantially do not overlap the first area of the CPU die. A multi-chip package having a DRAM cache disposed on the substrate and a CPU die disposed on the DRAM cache is also disclosed.
Abstract:
A flash memory device having at least one bank, where the each bank has an independently configurable page size. Each bank includes at least two memory planes having corresponding page buffers, where any number and combination of the memory planes are selectively accessed at the same time in response to configuration data and address data. The configuration data can be loaded into the memory device upon power up for a static page configuration of the bank, or the configuration data can be received with each command to allow for dynamic page configuration of the bank. By selectively adjusting a page size the memory bank, the block size is correspondingly adjusted.
Abstract:
A semiconductor memory device including a plurality of memory die and a controller die. The controller die is connected to an internal control bus. The controller die is configured to provide to a selected one of the memory die an internal read command responsive to an external read command. The selected memory die is configured to provide read data to the controller in response to the internal read command; wherein latency between receipt by the controller die of the external read command and receipt of the read data from the selected memory die differs for at least two of the memory die when selected as the selected memory die.
