Appl. No.:

13/468957

Inventors:

Darmin Jin - Fremont CA, US
William Chau - San Jose CA, US
Brian Cheung - San Bruno CA, US

Assignee:

SANDISK TECHNOLOGIES INC. - Plano TX

International Classification:

H03L 5/00
H03K 17/56

US Classification:

327333, 327419

Abstract:

Apparatus and method for coupling high voltages for a semiconductor device via high voltage switches are disclosed. A high voltage switch includes a switch and a level shifter. The switch is defined between a voltage source and a voltage output. An enable line is coupled to a first transistor of the switch. The level shifter includes an input and an output. A characterization line is coupled to the input of the level shifter and the output of the level shifter is coupled to a second transistor of the switch. The level shifter further includes a power rail that is coupled to the switch between the first transistor and the second transistor.

Abstract:

A usage management system for tracking usage of applications available to subscribers of an interactive network includes an application server adapted to process a plurality of applications on demand by the users. The application server generates a plurality of event records each event record including at least one active domain identifier representing a domain being executed. Each domain represents an executable logical location within an application. A usage processing server is coupled to the application server, which is adapted to receive signals from the application server corresponding to the generated event records. The usage processing server is further adapted to track the time of occurrence of each domain identified in each event record.
