CURRENT STEERING IN READING MAGNETIC TUNNEL JUNCTION - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18332674 Titled 'CURRENT STEERING IN READING MAGNETIC TUNNEL JUNCTION'
Simplified Explanation
The abstract describes a type of read circuit for a magnetic tunnel junction (MTJ) device. The circuit includes a current steering element that is connected to the read path. The current steering element maintains a larger current at one node to ensure reliable voltage or current sensing. At the other node, a smaller current is maintained, which passes through the MTJ structure. The current at the first node is proportional to the current at the second node, allowing the current at the first node to be used to infer the current at the second node, which is affected by the resistance value of the MTJ.
Original Abstract Submitted
The disclosed MTJ read circuits include a current steering element coupled to the read path. At a first node of the current steering element, a proportionally larger current is maintained to meet the requirements of a reliable voltage or current sensing. At a second node of the current steering element, a proportionally smaller current is maintained, which passes through the MTJ structure. The current at the first node is proportional to the current at the second node such that sensing the current at the first node infers the current at the second node, which is affected by the MTJ resistance value.
