Avago Technologies General IP/Broadcom Assigned Three Patents

Programming embedded flash storage device
Avago Technologies General IP (Singapore) PTE. Ltd., Singapore, Singapore, Broadcom, Inc., has been assigned a patent (10,120,792) developed by Segal, Avigdor, Netanya, Israel, Weingarten, Hanan, Herzelia, Israel, Maly, Igal, Tel Aviv, Israel, and Shemesh, Irena, Haifa, Israel, for a “programming an embedded flash storage device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method that includes sending to an embedded flash storage device, (EFSD) and during a transaction, a data unit and recovery metadata that differs from a flash memory unit memory management data structure, FMUMMDS, instructing the EFSD to program the data unit and the recovery metadata to a group of flash memory cells, sending to the host computer a transaction completion indication in response to a successful completion of the programming and before a completion of a management process that comprises updating by the flash memory controller, the FMUMMDS to reflect, (a) the recovery metadata and, (b) physical address information related to the group of the flash memory cells, and programming, by the EFSD, the FMUMMDS to the flash memory unit, wherein the data structure is reconstructible based upon the recovery metadata and the physical address information related to the group of the flash memory cells.”

The patent application was filed on January 29, 2014 (14/167,879).

Non-volatile memory cell having multiple signal pathways
Avago Technologies General IP (Singapore) PTE. Ltd., Singapore, Singapore, has been assigned a patent (10,109,364) developed by Schmitt, Jonathan A., Eden Prairie, MN, and Tseng, Jermyn, Irvine, CA, for a “non-volatile memory cell having multiple signal pathways to provide access to an antifuse of the memory cell.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A non-volatile memory cell, having an antifuse for storing data, is disclosed for use in a non-volatile data storage device. The non-volatile memory cell includes multiple redundant signal pathways to provide redundant access to the antifuse. During operation, the non-volatile memory cell can access the antifuse using a first signal pathway from among the multiple redundant signal pathways. However, when the first signal pathway is inoperable, the non-volatile memory cell is able to access the antifuse using a second signal pathway from among the multiple redundant signal pathways. The non-volatile memory cell is fabricated using a continuous region of one or more diffusion layers to allow efficient connection to other non-volatile memory cells to form an array of memory cells for the non-volatile data storage device.”

The patent application was filed on October 28, 2015 (14/925,543).

Soft data based flash memory data recovery
Avago Technologies General IP (Singapore) PTE. Ltd., Singapore, Singapore, has been assigned a patent (10,108,489) developed by Zhao, Zhijun, Fremont, CA, Yang, Shaohua, San Jose, CA, and Krachkovsky, Victor, Allentown, PA, for “systems and methods for efficient soft data based flash memory data recovery.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Embodiments are related to systems and methods for data storage, and more particularly to systems and methods for storing and accessing data from a flash memory.”

The patent application was filed on October 28, 2015 (14/925,714).
