Non-sequential page continuous read

Abstract

A memory device such as a page mode NAND flash including a page buffer, and an input/output interface for I/O data units having an I/O width less than the page width supports continuous page read with non-sequential addresses. A controller controls a continuous page read operation to output a stream of pages at the I/O interface. The continuous read operation includes responding to a series of commands to output a continuous stream of pages. The series of commands including a first command and a plurality of intra-stream commands received before completing output of a preceding page in the stream. The first command includes an address to initiate the continuous page read operation, and at least one intra-stream command in the plurality of intra-stream commands includes a non-sequential address to provide the non-sequential page in the stream of pages.
