Split-Word Memory

摘要

Method, process, and apparatus to efficiently store, read, and/or process syllables of word data. A portion of a data word, which includes multiple syllables, may be read by a computer processor. The processor may read a first syllable of the data word from a first memory. The processor may read a second syllable of the data word from a second portion of memory. The second syllable may include bits which are less critical than the bits of the first syllable. The second memory may be distinct from the first memory based on one or more physical attributes.
