Publication number: 20150309927Abstract: A hybrid non-volatile system uses non-volatile memories based on two or more different non-volatile memory technologies in order to exploit their relative advantages. In an exemplary embodiment, the memory system includes a controller and a flash memory, where the controller has a non-volatile RAM based on an alternate technology such as FeRAM. The flash memory is used for the storage of user data and the non-volatile RAM in the controller is used for system control data. The use of an alternate non-volatile memory technology in the controller allows for a non-volatile copy of the most recent control data to be accessed more quickly as it can be updated on a bit by bit basis. In another exemplary embodiment, the alternate non-volatile memory is used as a cache where data can safely be staged prior to its being written to the memory or read back to the host.Type: ApplicationFiled: June 12, 2015Publication date: October 29, 2015Inventors: Alan Welsh Sinclair, Sergey Anatolievich Gorobets, Kevin Conley, Carlos J.

Patent number: 9122591Abstract: The present invention present methods and architectures for the pipelining of read operation with write operations. In particular, methods are presented for pipelining data relocation operations that allow for the checking and correction of data in the controller prior to its being re-written, but diminish or eliminate the additional time penalty this would normally incur. A number of architectural improve are described to facilitate these methods, including: introducing two registers on the memory where each is independently accessible by the controller; allowing a first memory register to be written from while a second register is written to; introducing two registers on the memory where the contents of the registers can be swapped.Type: GrantFiled: December 13, 2013Date of Patent: September 1, 2015Assignee: SanDisk Technologies Inc.Inventors: Sergey Gorobets, Kevin Conley

Patent number: 8745322Abstract: A non-volatile memory system of a type having blocks of memory cells erased together and which are programmable from an erased state in units of a large number of pages per block. If the data of only a few pages of a block are to be updated, the updated pages are written into another block provided for this purpose. Updated pages from multiple blocks are programmed into this other block in an order that does not necessarily correspond with their original address offsets. The valid original and updated data are then combined at a later time, when doing so does not impact on the performance of the memory. If the data of a large number of pages of a block are to be updated, however, the updated pages are written into an unused erased block and the unchanged pages are also written to the same unused block. By handling the updating of a few pages differently, memory performance is improved when small updates are being made.Type: GrantFiled: June 28, 2013Date of Patent: June 3, 2014Assignee: SanDisk Technologies Inc.Inventors: Kevin Conley, Carlos J.

Patent number: 8126527Abstract: This document discusses, among other things, quantification of hemoglobin content, and therefore blood volume, of muscle. An analysis of the optical spectra can determine the ratio of hemoglobin (Hb) to myoglobin (Mb) content in intact muscle. The peak position of the in vivo optical spectra from intact tissue is used to determine the ratio of Hb to Mb contributing to the optical signal. The wavelength of the peak is a linear function of the percent contribution of Hb to the optical spectra. Such analysis in combination with known Mb concentrations yields a non-invasive measure of the Hb content for in vivo muscle.Type: GrantFiled: August 3, 2006Date of Patent: February 28, 2012Assignee: University of Washington through its Center for CommercializationInventors: David J. Marcinek, Kevin Conley, Kenneth A. Schenkman

Patent number: 8001325Abstract: A removable data storage device that intelligently operates as one large data storage region or as multiple, smaller data storage regions is disclosed. The removable data storage device can be used in not only modern electronic products (using 32-bit addressing) but also legacy products (using 16-bit addressing). A host device can couple to the removable storage device to access data stored in/to the removable storage device. As an example, the removable data storage device can be a memory card.Type: GrantFiled: January 9, 2004Date of Patent: August 16, 2011Assignee: SanDisk CorporationInventors: Kevin Conley, Robert Chang, Wes G.

Publication number: 20080065818Abstract: The present invention presents a non-volatile memory and method for its operation that ensures reliable mechanism for write and erase abort detection in the event of lost of power during non-volatile memory programming and erasing with minimized system performance penalty. During a multi-sector write process, an indication of a successful write in one sector is written into the overhead of the following sector at the same time as the following sector's data content is written. The last sector written will additionally have an indication of its own successful write written into its overhead. For erase, an erase abort flag in the first sector of the block can be marked after a successful erase operation.Type: ApplicationFiled: November 7, 2007Publication date: March 13, 2008Inventors: Jason Lin, Kevin Conley, Robert Chang

Publication number: 20070266200Abstract: A system and methods are given for providing information on the amount of life remaining for a memory having a limited lifespan, such as a flash memory card. For example, it can provide a user with the amount of the memory's expected remaining lifetime in real time units (i.e., hours or days) or as a percentage of estimated initial life. An end of life warning can also be provided. In a particular embodiment, the amount of remaining life (either as a percentage or in real time units) can be based on the average number of erases per block, but augmented by the number of spare blocks or other parameters, so that an end of life warning is given if either the expected amount of remaining life falls below a certain level or the number of spare blocks falls below a safe level.Type: ApplicationFiled: May 15, 2006Publication date: November 15, 2007Inventors: Sergey Gorobets, Kevin Conley

Publication number: 20070266296Abstract: Data are encoded using convolutional coding prior to storage in a nonvolatile memory array, so that errors that occur when the data are read may be corrected even where there is a large number of such errors. Coding rates of less than one increase the amount of data to be stored but allow correction of large numbers of errors.Type: ApplicationFiled: May 15, 2006Publication date: November 15, 2007Inventor: Kevin Conley

Publication number: 20070211532Abstract: In order to maintain the integrity of data stored in a flash memory that are susceptible to being disturbed by operations in adjacent regions of the memory, disturb events cause the data to be read, corrected and re-written before becoming so corrupted that valid data cannot be recovered. The sometimes conflicting needs to maintain data integrity and system performance are balanced by deferring execution of some of the corrective action when the memory system has other high priority operations to perform. In a memory system utilizing very large units of erase, the corrective process is executed in a manner that is consistent with efficiently rewriting an amount of data much less than the capacity of a unit of erase.Type: ApplicationFiled: May 14, 2007Publication date: September 13, 2007Inventors: Carlos Gonzalez, Kevin Conley

Publication number: 20070180062Abstract: A portable media encoder with a remote setup management interface is disclosed. The encoder provides a video input port configured to receive a video input from a video input source, an audio input port configured to receive an audio input from an audio input source, and a digital output port for providing a digital output stream corresponding to the received video input and audio input. An encoding processor converts the video input and the audio input into a streamable digital output format for transmitting through the digital output port, and a digital control input port for receives commands from a remote management computer over the Internet using a web browser and provides the commands to the encoding processor. A housing encloses the processor and provides at least one access panel providing user access to the video input port, the audio input port, the digital output port, and the digital control input port.Type: ApplicationFiled: April 6, 2006Publication date: August 2, 2007Inventors: Rick Southerland, Mark Fears, Mark Hershey, Chris McCauley, Kevin Conley, Kevin Hartman, Jeremy Gerdes
