  • Publication number: 20140370664
    Abstract: Techniques for fabricating cross-point memory devices are disclosed in which word line (WL) and/or bit line (BL) processing is separate from cross-point memory memory-material processing, thereby providing an advantageous increase in thickness of the WL and/or BL metal that avoids an increase in the WL and BL resistances as feature sizes for cross-point memories scale smaller.

  • Publication number: 20140340963
    Abstract: Apparatus and methods are disclosed, such as an apparatus that includes a string of charge storage devices associated with a pillar (e.g., of semiconductor material), a source gate device, and a source select device coupled between the source gate device and the string. Additional apparatus and methods are described.

  • Publication number: 20140217488
    Abstract: A 3-D memory array comprises a plurality of elevationally extending strings of memory cells. An array of select devices is elevationally over and individually coupling with individual of the strings. The select devices individually comprise a channel, gate dielectric proximate the channel, and gate material proximate the gate dielectric. The individual channels are spaced from one another. The gate material comprises a plurality of gate lines running along columns of the spaced channels elevationally over the strings. Dielectric material is laterally between immediately adjacent of the gate lines. The dielectric material and the gate lines have longitudinally non-linear edges at an interface relative one another. Additional embodiments are disclosed.

  • Publication number: 20120117306
    Abstract: Memory devices, methods for programming sense flags, methods for sensing flags, and memory systems are disclosed. In one such memory device, the odd bit lines of a flag memory cell array are connected with a short circuit to a dynamic data cache. The even bit lines of the flag memory cell array are disconnected from the dynamic data cache. When an even page of a main memory cell array is read, the odd flag memory cells, comprising flag data, are read at the same time so that it can be determined whether the odd page of the main memory cell array has been programmed. If the flag data indicates that the odd page has not been programmed, threshold voltage windows can be adjusted to determine the states of the sensed even memory cell page.
