Cross-Decoding For Non-Volatile Storage

US Patent:
2012015, Jun 14, 2012
Filed:
Dec 12, 2011
Appl. No.:
13/323769
Inventors:
Yan LI - San Jose CA, US
Hao ZHONG - Milpitas CA, US
International Classification:
H03M 13/09, H03M 13/05, G06F 11/10, G06F 11/00
US Classification:
714704, 714807, 714773, 714E11004, 714E11035
Abstract:
Cross-decoding assists decoding of an otherwise uncorrectable error when decoding a desired page of a multi-level-cell technology flash memory. A solid-state disk (SSD) controller adjusts space allocated to redundancy respectively within various pages (e.g. upper, middle, and lower pages) such that the respective pages have respective effective Bit Error Rates (BER)s, optionally including cross-decoding, that approach one another. Alternatively the controller adjusts the allocation to equalize decoding time (or alternatively access time), optionally including decoding time (accessing time) accrued as a result of cross-decoding when there is an otherwise uncorrectable error. The adjusting is via (a) respective ratios between allocation for ECC redundancy and user data space, and/or (b) respective coding rates and/or coding techniques for each of the various pages. Alternatively the controller adjusts the allocation to maximize total usable capacity by allocating to redundancy and data for the various pages, assuming that cross-decoding is to be used.

Humanized Antibodies Against Vascular Endothelial Growth Factor

US Patent:
7667004, Feb 23, 2010
Filed:
Nov 26, 2003
Appl. No.:
10/723434
Inventors:
Pingyu Zhong - Mountain View CA, US
Peizhi Luo - Sunnyvale CA, US
Kevin C. Wang - San Francisco CA, US
Mark Hsieh - San Francisco CA, US
Yan Li - San Jose CA, US
Assignee:
Abmaxis, Inc. - Mountain View CA
International Classification:
C12P 21/08
US Classification:
5303881, 530350, 5303873
Abstract:
Methods are provided for designing and selecting antibodies against human antigens with high affinity and specificity in silico and in vitro. In some particular embodiments, methods are provided for designing and selecting humanized or fully human antibodies against vascular endothelial growth factor (VEGF) with high affinity and specificity. In another aspect of the invention, monoclonal antibodies against VEGF are provided. In particular, humanized or human anti-VEGF monoclonal antibodies are provided with ability to bind to human VEGF with high affinity, inhibit VEGF-induced proliferation of endothelial cells in vitro and inhibit VEGF-induced angiogenesis in vivo. These antibodies and their derivative can be used in a wide variety of applications such as diagnosis, prevention, and treatment of diseases such as cancer, AMD, diabetic retinopathy, and other diseases derived from pathological angiogenesis.

Ldpc Erasure Decoding For Flash Memories

US Patent:
2013013, May 30, 2013
Filed:
Mar 11, 2011
Appl. No.:
13/583617
Inventors:
Hao Zhong - Milpitas CA, US
Yan Li - San Jose CA, US
Radoslav Danilak - Cupertino CA, US
Earl T. Cohen - Oakland CA, US
Assignee:
LSI CORPORATION - Milpitas CA
International Classification:
G06F 11/10
US Classification:
714773
Abstract:
A Solid-State Disk (SSD) controller uses LDPC decoding to enable flash memory accesses with improved latency and/or error correction capabilities. With SLC flash memory having a BER less than a predetermined value, the SSD controller uses a 1-bit read (single read) hard-decision LDPC decoder to access the flash memory. If the hard-decision LDPC decoder detects an uncorrectable error, then the SSD controller uses a 1.5-bit read (two reads) erasure-decision LDPC decoder to access the flash memory. With flash memory having a raw BER between two other predetermined values, the SSD controller omits the use of the hard-decision LDPC decoder and uses only the erasure-decision LDPC decoder to access the flash memory. Variations of the SSD controller similarly access MLC flash memory. Some SSD controllers dynamically switch between hard-decision and erasure-based decoders based on dynamic decoder selection criteria.

Measuring Cell Damage For Wear Leveling In A Non-Volatile Memory

US Patent:
2014008, Mar 20, 2014
Filed:
Sep 15, 2012
Appl. No.:
13/620982
Inventors:
Yan LI - San Jose CA, US
Alexander HUBRIS - San Jose CA, US
Hao ZHONG - Milpitas CA, US
Assignee:
LSI CORPORATION - Milpitas CA
International Classification:
G06F 11/16
US Classification:
714773
Abstract:
An NVM controller measures cell damage for wear leveling in an NVM, thus improving performance, reliability, lifetime, and/or cost of a storage sub-system, such as an SSD. In a first aspect, the controller determines that an error reading a page of NVM was caused by cell damage and/or cell leakage. The controller reprograms and immediately reads back the page, detecting that the error was caused by cell damage if an error is detected during the immediate read. In a second aspect, the cell damage is tracked by updating cell damage counters for pages and/or blocks of NVM. In a third aspect, wear leveling is performed based at least in part upon measured cell damage for pages and/or blocks of NVM.
