Filed:

Apr 26, 2002

Appl. No.:

10/133851

Inventors:

Dean L. Field - Graham WA
Larry Lynn Hinton - Bothell WA
John Kizziar, III - Cheyenne WY

Assignee:

Cypress Semiconductor Corp. - San Jose CA

International Classification:

H03L 706

US Classification:

327156, 327157, 327 42, 327142

Abstract:

An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to receive a device input signal. The apparatus may be configured to perform a predefined function in response to the device input signal during normal operation. The second circuit may be configured to determine when the device input signal is invalid according to a predetermined parameter. The second circuit may be configured to generate a function control signal in response to the predetermined parameter. The function control signal may be configured to direct the apparatus to perform a second predetermined function. The second predetermined function may be different than the first predetermined function.

Assignee:

Cypress Semiconductor Corporation - San Jose CA

International Classification:

H01L 29/78

US Classification:

257416, 257414, 310313 R, 310313 B

Abstract:

An integrated circuit is provided which includes one or more device elements formed above a base substrate, a structure forming a sealed cavity above at least a portion of the one or more device elements, and one or more conductive devices formed above the sealed cavity. A method for fabrication of such an integrated circuit is also provided. An exemplary embodiment of the integrated circuit includes a surface acoustic wave device having a plurality of tracks each with a first interdigitated transducer configured to convert a receiving electric field energy into mechanical wave energy and a second interdigitated transducer configured to convert the mechanical wave energy into an output electric field energy. The SAW device also includes a conductor arranged above and spanning across at least two tracks of the plurality of tracks and coupled to the first interdigitated transducers of at least the two tracks.

Assignee:

Cypress Semiconductor Corp. - San Jose CA

International Classification:

H03L 706

US Classification:

327156

Abstract:

A semiconductor device (e. g. , a zero-delay buffer) is provided which is capable of reducing current or power consumption without the use of a dedicated pin. The device may include a frequency detector that receives a detector input signal corresponding to or derived from a device input signal. The device input signal performs a first function during normal operation of the device. The detector determines whether the frequency of the detector input signal is less than a predetermined minimum, and if so, generates a power down signal configured to direct the device to reduce current or power consumption in at least one of its component circuits. The frequency detector may include a "one-shot" circuit responsive to the detector input signal for generating a frequency indicator signal, and a "power down" signal output circuit responsive to the frequency indicator signal for generating the power down signal.
