Abstract
A magnetoresistive electrostatic discharge (ESD) event detector includes at least one magnetoresistive device. The at least one magnetoresistive device detects an ESD event in an ESD sensitive device based on magnetoresistive properties of the at least one magnetoresistive device. The magnetoresistive device has an ESD failure level that is lower than the ESD failure level of said ESD sensitive device.
Claims12
A magnetoresistive electrostatic discharge (ESD) event detector comprising:
- at least one magnetoresistive device, wherein said at least one magnetoresistive device detects an ESD event in an ESD sensitive device based on magnetoresistive properties of said at least one magnetoresistive device, and wherein said at least one magnetoresistive device comprises an ESD sensitivity level that is greater than an ESD sensitivity level of said ESD sensitive device, wherein said ESD sensitivity level of said at least one magnetoresistive device is adjustable based at least in part on a group consisting of:
- a cross-sectional area of said at least one magnetoresistive device and a thickness of said at least one magnetoresistive device.
A magnetoresistive electrostatic discharge (ESD) event detector comprising:
- at least one magnetoresistive device, wherein said at least one magnetoresistive device detects an ESD event in an ESD sensitive device based on magnetoresistive properties of said at least one magnetoresistive device, wherein said at least one magnetoresistive device comprises an ESD sensitivity level that is greater than an ESD sensitivity level of said ESD sensitive device, said at least one magnetoresistive device electrically coupled to said ESD sensitive device, wherein said ESD sensitive device is potentially subject to said ESD event and wherein said at least one magnetoresistive device is a plurality of magnetoresistive devices electrically coupled in parallel to said ESD sensitive device, wherein each of said plurality of magnetoresistive devices comprises a different ESD sensitivity level.
