US Patent:
7927994, Apr 19, 2011
Filed:
Dec 6, 2010
Appl. No.:
12/961193
Inventors:
Xian Liu - Sunnyvale CA, US
Amitay Levi - Cupertino CA, US
Alexander Kotov - Sunnyvale CA, US
Yuri Tkachev - Sunnyvale CA, US
Viktor Markov - Sunnyvale CA, US
James Yingbo Jia - Fremont CA, US
Chien-Sheng Su - Saratoga CA, US
Yaw Wen Hu - Cupertino CA, US
Assignee:
Silicon Storage Technology, Inc. - Sunnyvale CA
International Classification:
H01L 21/4763
US Classification:
438594, 257320, 257E29129
Abstract:
An improved split gate non-volatile memory cell is made in a substantially single crystalline substrate of a first conductivity type, having a first region of a second conductivity type, a second region of the second conductivity type, with a channel region between the first region and the second region in the substrate. The cell has a select gate above a portion of the channel region, a floating gate over another portion of the channel region, a control gate above the floating gate and an erase gate adjacent to the floating gate. The erase gate has an overhang extending over the floating gate. The ratio of the dimension of the overhang to the dimension of the vertical separation between the floating gate and the erase gate is between approximately 1. 0 and 2. 5, which improves erase efficiency.

US Patent:
8423592, Apr 16, 2013
Filed:
Apr 11, 2008
Appl. No.:
12/101569
Inventors:
Junzhi Wang - San Jose CA, US
Alon Marcu - Tel-Mond, IL
Ori Stern - Modeen, IL
Susan A. Cannon - Santa Cruz CA, US
Xian Jun Liu - San Jose CA, US
Po Yuan - Milpitas CA, US
Assignee:
SanDisk Technologies Inc. - Plano TX
International Classification:
G06F 12/00
G06F 17/30
G06F 15/16
US Classification:
707822, 711101
Abstract:
In order to write data to a storage system accessible with a first and second file system, a manager receives a data write request associated with a file. The manager determines if a function supported by the second file system is needed to complete the write request. If so, the file is opened and extended with the first file system. The file is then opened and written to by the second file system. The file is truncated by the first file system, and closed by both file systems. If the second file system function is not needed, the file is opened, written, and closed by the first file system. In order to read data from a storage system using a function supported by the second file system, the second file system's cached storage system index is updated, and then the file is opened, read, and closed by the second file system.

View page
US Patent:
8433734, Apr 30, 2013
Filed:
Jun 29, 2009
Appl. No.:
12/494233
Inventors:
Xian Jun Liu - San Jose CA, US
Po Yuan - Milpitas CA, US
Assignee:
Sandisk Technologies Inc. - Plano TX
International Classification:
G06F 17/30
US Classification:
707824, 707694, 707812
Abstract:
Systems and methods of identifying a file path of a removable storage device are disclosed. A method includes, at a host device that is coupled to the removable storage device, selecting a file path that is associated with the removable storage device by accessing a size associated with a root directory accessible to the host device, where the root directory corresponds to the removable storage device. The file path is selected based upon the size associated with the root directory. The selected file path is verified by initiating a memory access operation using the selected file path.

Controlled Data Access To Non-Volatile Memory

Abstract:
A method of controlling data access to non-volatile memory is disclosed. The method includes storing a data file in a non-volatile memory. The non-volatile memory includes a memory array including a plurality of address ranges one or more of which corresponding to a protected portion of the memory array and one or more of which corresponding to an unprotected portion of the memory array. The method also includes communicating to a host device an indication that a memory request with respect to the protected portion of the memory array is denied. The indication is communicated for instructing the host device to avoid a timeout when the memory request is denied.

Filed:
Dec 23, 2008
Appl. No.:
12/342965
Inventors:
Ahmet Altay - Mountain View CA, US

Robert Chin-Tse Chang - Danville CA, US
Xian Jun Liu - San Jose CA, US
Oktay Rasizade - Castro Valley CA, US

Assignee:
SanDisk Technologies Inc. - Plano TX
International Classification:
H04L 29/06
US Classification:
726 18, 455410, 455411, 455 261
Abstract:
A method and system of controlling access to a hardware or software feature provided by a host is disclosed. An application seeking authorization to access a feature transmits a credential and an index to a host agent within the host. The index is associated with the requested feature. The host agent reads credential validation data from a storage location corresponding to the index in a non-volatile storage device in communication with the host. The validity of the credential is determined based on the credential validation data, and an authorization is transmitted if the credential is valid. A third party can control the outcome of the validity determination by sending an instruction to the host to replace the credential validation data with invalid data that causes the validity test to fail. The third party can also control the non-volatile storage device data used by the application to calculate the credential.
