Patent number: 10109347Abstract: A variable resistance memory array, programming a variable resistance memory element and methods of forming the array. A variable resistance memory array is formed with a plurality of word line transistors surrounding each phase change memory element. To program a selected variable resistance memory element, all of the bitlines are grounded or biased at the same voltage. A top electrode select line that is in contact with the selected variable resistance memory element is selected. The word line having the word line transistors surrounding the selected variable resistance memory element are turned on to supply programming current to the element. Current flows from the selected top electrode select line through the variable resistance memory element into the common source/drain region of the surrounding word line transistors, across the transistors to the nearest bitline contacts. The word lines are patterned in various lattice configurations.Type: GrantFiled: November 13, 2015Date of Patent: October 23, 2018Assignee: OVONYX MEMORY TECHNOLOGY, LLCInventor: Jun Liu

Patent number: 9715419Abstract: This disclosure relates to selectively performing a read with increased accuracy, such as a self-reference read, from a memory. In one aspect, data is read from memory cells, such as magnetoresistive random access memory (MRAM) cells, of a memory array. In response to detecting a condition associated with reading from the memory cells, a self-reference read can be performed from at least one of the memory cells. For instance, the condition can indicate that data read from the memory cells is uncorrectable via decoding of error correction codes (ECC). Selectively performing self-reference reads can reduce power consumption and/or latency associated with reading from the memory compared to always performing self-reference reads.Type: GrantFiled: April 8, 2015Date of Patent: July 25, 2017Assignee: OVONYX MEMORY TECHNOLOGY, LLCInventors: Wayne Kinney, Gurtej S.
