  • Publication number: 20150103601
    Abstract: Disclosed herein are system, method and computer program product embodiments for utilizing soft programming a nonvolatile memory. An embodiment operates by sequentially applying a single soft programming voltage pulse to all memory cells along each word line in the nonvolatile memory that fail soft programming verification in a first phase. This sequential application of the single soft programming voltage pulse in the first phase may repeat a predetermined number of times or until a threshold is met. Once the predetermined number of times completes, or the threshold is met, soft programming proceeds to a second phase where soft programming remains with each word line until all memory cells along the word line passes soft programming verification.

  • Publication number: 20150106664
    Abstract: Disclosed herein are system, apparatus, methods and/or combinations and sub-combinations thereof, for using a read data strobe signal received at a host device from a peripheral device to convey variable latency (flow) control or report an error in the data content read from the peripheral device. Reception of the read data strobe signal before a predetermined maximum latency time, provides variable latency control back to the host by indicating when valid data is available for capture. If the read data strobe signal is not received before expiration of a predetermined maximum latency time, the peripheral controller is indicating a read data error back to the host.

  • Publication number: 20150097245
    Abstract: A system and method for providing electrical isolation between closely spaced devices in a high density integrated circuit (IC) are disclosed herein. An integrated circuit (IC) comprising a substrate, a first device, a second device, and a trench in the substrate and a method of fabricating the same are also discussed. The trench is self-aligned between the first and second devices and comprises a first filled portion and a second filled portion. The first fined portion of the trench comprises a dielectric material that forms a buried trench isolation for providing electrical isolation between the first and second devices. The self-aligned placement of the buried trench isolation allows for higher packing density without negatively affecting the operation of closely spaced devices in a high density IC.

  • Publication number: 20150098290
    Abstract: Disclosed are methods, circuits, apparatuses and systems for providing power to a dynamic load such as a non-volatile memory array. According to embodiments, a voltage source may be adapted to generate and output a supply current at substantially a target voltage through a regulating transistor whose channel is in series between an output terminal of said charge pump and an input terminal of said NVM array. A discharge circuit branch coupled to an output terminal of the regulating transistor may be adapted to drain away current from the regulating transistor output terminal when a voltage at the regulating transistor output terminal exceeds a first defined threshold voltage. A bulk regulating circuit branch coupled to a bulk of the regulating transistor may be adapted to reduce a bulk-voltage of the regulating transistor when a voltage at the regulating transistor output terminal exceeds a defined threshold voltage.

  • Publication number: 20150091138
    Abstract: A semiconductor may include several vias located in an active region and a die seal region. In the active region, a photoresist can be patterned with openings corresponding to the vias. In the die seal area, however, the photoresist can be patterned to overlap the vias. With this configuration, an underlayer etch will not affect an underlayer resist in the die seal area, allowing the die seal area to be disregarded for purposes of calculating a process window.

  • Patent number: 8984238
    Abstract: Efficient and convenient storage systems and methods are presented. In one embodiment, a fractured erase process is performed in which a pre-program process, erase process and soft program process are initiated independently. Memory cells can be pre-programmed and conditioned independent of an erase command. The initiation of the independent pre-programming is partitioned from an erase command which is partitioned from initiation of a soft-programming command. A cell is erased wherein the erasing includes erase operations that are partitioned from the pre-preprogramming process. In one embodiment, the independent pre-program process is run in the background.
