摘要： A method and system for programming and reading a magnetic memory is disclosed. The magnetic memory includes a plurality of selectable word line segments and a plurality of magnetic storage cells corresponding to each word line segment. The method and system include reading the magnetic storage cells corresponding to a word line segment to determine a state of each magnetic storage cell. The method and system also include writing data to a portion of the magnetic cells corresponding to the word line segment after the reading. The method and system also include rewriting the state to each of a remaining portion of the magnetic storage cells corresponding to the word line segments at substantially the same time as the portion of the magnetic cells are written.

摘要： A method and system for providing a magnetic memory are disclosed. The method and system include providing a plurality of magnetic memory cells and at least one programmable current source. Each of the plurality of magnetic memory cells includes a first magnetic element. The programmable current source(s) are for programming a portion of the plurality of magnetic memory cells. Each of the programmable current source(s) includes a controller and a current source coupled to the controller. The controller is for determining a current provided by the current source and includes at least a second magnetic element. The second magnetic element(s) are substantially the same as the first magnetic element. The controller determines the current provided by the current source based on the at least the second magnetic element.

摘要： A method and system for providing a magnetic memory including magnetic memory cells associated with a word line segment is disclosed. The magnetic memory cell includes a magnetic storage device and an isolation device. The isolation device is coupled to the magnetic tunneling junction and with a combined word line for reading and writing to the magnetic memory cell. The magnetic storage device and the isolation device are configured such that no direct current path to ground exists during the writing to the magnetic memory cell. In one aspect, in a write mode, the combined word line associated with the word line segment and the word line segment are activated. In the read mode, at least a portion of the memory cells associated with the word line segment are selected using the combined word line.
