Sentences with phrase «tantalum oxide»
"Tantalum oxide" refers to a compound made by combining the chemical element tantalum with oxygen. It is often used in electronic devices, such as smartphones, because it can help enhance their performance and make them smaller and more efficient. Full definition
While researchers already knew the potential value of tantalum oxide for memories, such arrays have been limited to about a kilobyte because denser memories suffer from crosstalk that allows bits to be misread.
