Abstract
A semiconductor memory having a page mode includes a first circuit for reading out page data from a memory cell array, in accordance with cell address signals A3-A19, and a second circuit for latching, at the beginning of a page mode cycle, page data to be read out in the cycle, sequentially outputting the latched data in page address signals A0-A2, and inputting to the first circuit an address from which to read out page data to be output in a following page mode cycle. By provision of the first and second circuits, the period of time from a change in address to output of read-out data can be shortened considerably, permitting high-speed reading in the page mode.
