摘要： A resistance random access memory (RRAM) having a source line shared structure and an associated data access method. The RRAM, in which a write operation of writing data of first state and second state to a selected memory cell is performed through first and second write paths having mutually opposite directions, includes word lines, bit lines, a memory cell array and a plurality of source lines. The memory cell array includes a plurality of memory cells each constructed of an access transistor coupled to a resistive memory device. The memory cells are disposed in a matrix of rows and columns and located at each intersection of a word line and a bit line. Each of the plurality of source lines is disposed between a pair of word lines and in the same direction as the word lines. A positive voltage is applied to a source line in a memory cell write operation. Through the source line shared structure, occupied chip area is reduced and, in a write operating mode, a bit line potential can be determined within a positive voltage level range.

摘要： Embodiments of the invention provide devices or methods that include a status bit representing an inversion of stored data. New data is written to selected cells, the new data is selectively inverted, and the status bit is selectively toggled, based on a comparison between pre-existing data and new data associated with a write command. A benefit of embodiments of the invention is that fewer memory cells must be activated in many instances (when compared to conventional art approaches). Moreover, embodiments of the invention may also reduce the average amount of activation current required to write to variable resistive memory devices and other memory device types.
