Patent number: 8305807Abstract: Techniques and corresponding circuitry are presented for the detection of broken wordlines in a memory array. In an exemplary embodiment, a program operation of the memory circuit is performed on a first plurality of memory cells along a word-line, where the programming operation includes a series of alternating programming pulses and verify operations, with the memory cells individually locking out from further programming pulses as verified. The determination of whether the word-line is defective based on the number of programming pulses for the memory cells of a first subset of the first plurality to verify as programmed relative to the number of programming pulses for the memory cells of a second subset of the first plurality to verify as programmed, where the first and second subsets each contain multiple memory cells and are not the same.Type: GrantFiled: July 9, 2010Date of Patent: November 6, 2012Assignee: SanDisk Technologies Inc.Inventors: Grishma Shailesh Shah, Yan Li

Patent number: 8307241Abstract: In a nonvolatile memory array, data is stored in multi-level cells (MLC) as upper-page data and lower-page data. Safe copies of both upper-page and lower-page data are stored in on-chip cache during programming. If a write fail occurs, data is recovered from on-chip cache. The controller does not have to maintain safe copies of data.Type: GrantFiled: June 16, 2009Date of Patent: November 6, 2012Assignee: SanDisk Technologies Inc.Inventors: Chris Nga Yee Avila, Jonathan Hsu, Alexander Kwok-Tung Mak, Jian Chen, Grishma Shailesh Shah

Publication number: 20110076225Abstract: A hydrogen generator capable of operating in any orientation and having no moving parts includes a catalyst retaining structure. The catalyst retaining structure is disposed in a housing and serves to separate the housing into a fuel holding portion and a hydrogen chamber. The catalyst retaining structure also includes one or more pores, each pore being in communication with the fuel holding and hydrogen chambers. A catalyst, that promotes the generation of hydrogen gas upon contact with the fuel, is disposed within the pores. The fuel enters the pores and thereupon generates hydrogen gas which passes into the hydrogen chamber. Contact of the fuel with the catalyst in the pores may be controlled and the position of the fuel-hydrogen interface within the pore may be moved so as to regulate the generation of hydrogen. The catalyst retaining structure can take different forms, including one or more hollow elongated members or plates, and may further incorporate hydrophobic and/or hydrophilic membranes.Type: ApplicationFiled: November 19, 2007Publication date: March 31, 2011Inventors: Shailesh A.
