Filed:

Apr 10, 2008

Appl. No.:

12/082280

Inventors:

Mike Chen - New York NY, US

Assignee:

Morgan Stanley - New York NY

International Classification:

G06F 35/00

US Classification:

705 35

Abstract:

Computer-implemented methods for valuing a derivative based on the BMA rate: the methods may comprise generating a model of the BMA/LIBOR ratio as a function of the LIBOR index, a stochastic noise function, and a seasonality process. The methods may also comprise solving the model for at least one value of the LIBOR index, and estimating a value of the derivative given the solution of the model. The value of the derivative may then be stored.

Abstract:

Certain embodiments include an etching method including providing an etch material, applying a gas mixture including hydrogen, forming a plasma, and etching the etch material. The etch material can include a low-k dielectric material. The gas mixture can include a hydrogen gas, a hydrogen-free fluorocarbon, and a nitrogen gas, and further include one or more of a hydrofluorocarbon gas, an inert gas, and/or a carbon monoxide gas. The hydrogen gas can be a diatomic hydrogen, a hydrocarbon, a silane and/or a fluorine-free hydrogen gas, including H, CH, CH, NH, and/or HO gases. The hydrogen-free fluorocarbon gas can be a CFgas (where x≧1 and Y≧1) and the hydrofluorocarbon gas can be a CHFgas (where x≧1, y≧1 and z≧1). The gas mixture can be free of oxygen. Embodiments can include reduced pressures, reduced hydrogen flow rates and one or more plasma frequencies.

Assignee:

Aplus Flash Technology, Inc. - Santa Clara CA

International Classification:

G11C 700
H03K 190175

US Classification:

36518911

Abstract:

In this invention external high voltages are connected to a chip containing a flash memory that are connected to selected cells to be erased. Internal pump circuits contained on the chip are turned off while the external voltages are used. The external voltages, a high negative voltage and a high positive voltage, are connected to gates and sources respectively of selected cells to be erased by a voltage control module. The external voltages are used during manufacture during program/erase operations to perform the erase function efficiently. The internal high voltage pump circuits are used to erase flash memory cells after being assembled on a circuit board by a user. Two level shifter circuits are disclosed that form a part of the voltage control module. The level shifter circuits apply voltages to the flash memory cells and provide voltages that select and deselect the cells for erasure.

Abstract:

Social media networking applications, web sites, and services creates implicit relationships between users based on their interest or participation in real-world and optionally virtual or online activities in addition to explicitly defined peer relationships. User profiles, activity entities, and expressions may be associated with metadata to assist in searching and navigation. Metadata is implicitly associated with user profiles, activity entities, expressions, or other data entities based on user behavior using metadata collector. A metadata collector is a poll, survey, list, questionnaire, census, test, game, or other type of presentation adapted to solicit user interaction. A metadata collector is associated with metadata elements. When users interact with a metadata collector, their user profiles and the data entities included in their interactions become associated with the metadata elements of the metadata collector. These metadata element associations may then be used for any purpose.

Assignee:

Datrium, Inc. - Sunnyvale CA

International Classification:

G06F 12/0891

Abstract:

In a processing system in which at least one entity issues data read and write requests to at least one storage system that stores data as data units, pluralities of data units are grouped. Each group is written as a respective cache line in a cache, which is deduplicated. Before evicting a selected one of the cache lines, a caching component determines whether at least one of the data units in the selected cache line is still active; if so, then the still active data unit(s) in the selected cache line is read and written to a different cache line.
