    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: A nonvolatile memory device comprises a first voltage generation unit, a second voltage generation unit, a first circuit block, and a discharge unit. The first voltage generation unit generates a first voltage with a first magnitude. The second voltage generation unit generates a second voltage with a second magnitude greater than the first magnitude. The first circuit block selectively receives the first voltage or the second voltage through an input node. The discharge unit discharges the input node between a time point where the input node has been charged with the second voltage and a time point where the input node receives the first voltage.
