Patents by Inventor SEUNGJUNE JEON

SEUNGJUNE JEON has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8683297
    Abstract: A method includes generating a replacement default read threshold at least partially based on a default read threshold and on an updated read threshold. The method also includes sending the replacement default read threshold to the memory.
    Type: Grant
    Filed: November 2, 2011
    Date of Patent: March 25, 2014
    Assignee: SanDisk Technologies Inc.
    Inventors: Seungjune Jeon, Steven Cheng
  • Patent number: 8644067
    Abstract: A method includes reading a representation of a codeword stored in a multi-level-cell (MLC) memory by comparing cell threshold voltages in the MLC memory to hard bit thresholds to generate hard bit values and to soft bit thresholds to generate soft bit values. The hard bit values and the soft bit values are provided to a non-binary decoder that uses probabilistic decoding to obtain decoded data.

  • Publication number: 20130151753
    Abstract: A method includes receiving hard bit data and soft bit data corresponding to a portion of a memory, where each storage element of the memory stores multiple bits per storage element. The hard bit data and the soft bit data is received in connection with reading a single bit of the multiple bits from each storage element in the portion of the memory based on one or more first read voltages. One or more second read voltages based on the hard bit data and the soft bit data are generated in response to a read voltage update operation. The memory reads data from the portion of the memory using the one or more second read voltages.

  • Publication number: 20130132798
    Abstract: An aliasing module is defined and connected to receive a first bit stream to be transmitted over a data bus from a memory to an external controller of the memory. The aliasing module is defined and connected to alias the first bit stream as a second bit stream and transmit the second bit stream over the data bus in lieu of the first bit stream. A de-aliasing module is defined and connected to receive the second bit stream from the data bus at the external controller. The de-aliasing module is defined and connected to de-alias the received second bit stream back to the first bit stream and provide the first bit stream to the external controller for processing.
