Abstract

A non-volatile memory is described that utilizes a cache read mode of operation, where a next page of memory is being read/sensed from the memory array by the sense amplifiers while a previously read page of memory is being read from the memory I/O buffer, wherein the next page is user selected. This random cache read mode allows for a memory with a random page read capability, in which the address of the next page of data to be read is user selectable, which benefits from the low latency of a cache read mode of operation due to concurrent data sensing and data I/O.
