Abstract:
1. A method for writing a magnetic random access memory-based ternary content addressable memory (MRAM-based TCAM) cell comprising: a first magnetic tunnel junction being formed from a storage layer having a magnetization, a sense layer having a magnetization direction adjustable relative to the magnetization of the storage layer, and an insulating layer between the storage and sense layers; a sense line coupled with the storage layer; a first field line and a second field line, both field lines being in communication with the storage and sense layers, and the first field line being orthogonal to the second field line; comprising: providing a first write data to said storage layer via the second field line to store a first stored data with a high or low logic state; and providing the first write data to said storage layer via the first field line to store the first stored data with a masked logic state.
