  • Pattern dependent write equalization
    Publication number: 20060232870
    Abstract: A pattern dependent write equalization method is disclosed. The method includes identifying a trait of a data pattern in a stream of write data. A characteristic of a write equalization signal is then defined according to the identified trait for the data pattern.
