摘要:
A memory device comprises first and second electrodes with a memory element and a buffer layer located between and electrically coupled to them. The memory element comprises one or more metal oxygen compounds. The buffer layer comprises at least one of an oxide and a nitride. Another memory device comprises first and second electrodes with a memory element and a buffer layer, having a thickness of less than 50 Å, located between and electrically coupled to them. The memory comprises one or more metal oxygen compounds. An example of a method of fabricating a memory device includes forming first and second electrodes. A memory, located between and electrically coupled to the first and the second electrodes, is formed; the memory comprises one or more metal oxygen compounds and the buffer layer comprises at least one of an oxide and a nitride.
