Abstract
A page buffer for a NAND memory array has a data register and a cache register that are suitably organized and operated to eliminate gaps and discontinuities in the output data during a continuous page read. The cache register may be organized in two portions, and the page data in the cache may be output from the cache portions in alternation. ECC delay may be eliminated from the output by performing the ECC computation on one cache portion while the other is being output. The data register may also be organized in two portions corresponding to the cache portions, so that data may be transferred to one cache portion while the other is being output. In a variation, the continuous page read may be done without ECC.
