  • Patent number: 10475511
    Abstract: Two-terminal memory can be formed into a memory array that contains many discrete memory cells in a physical and a logical arrangement. Where each memory cell is isolated from surrounding circuitry by a single transistor, the resulting array is referred to as a 1T1R memory array. In contrast, where a group of memory cells are isolated from surrounding circuitry by a single transistor, the result is a 1TnR memory array. Because memory cells of a group are not isolated among themselves in the 1TnR case, bit disturb effects are theoretically possible when operating on a single memory cell. Read operations are disclosed for two-terminal memory devices configured to mitigate bit disturb effects, despite a lack of isolation transistors among memory cells of an array. Disclosed operations can facilitate reduced bit disturb effects even for high density two-terminal memory cell arrays.
