Abstract
In a non-volatile memory circuit, read and write performance is improved by increasing the transfer rate of data through the cache buffer during read and write operations. In an array structure where memory cells are connected along bit lines, and the bit lines organized into columns, pairs of data words are stored interleaved on the bit lines of a pair of columns. Data is transferred in and out of the read and write circuit on an internal bus structure, where part of the transfer of one word stored on a pair of columns can overlap with part of the transfer of another word, accelerating transfer times for both read and write.
