Memory device

Abstract

Abstract PURPOSE:To simplify reading and writing by supplying a column address strobe signal at a reverse phase after row address strobe signals are supplied in a page mode to N-number of memory blocks divided into two parts each. CONSTITUTION:Digital color video signals of one frame written on memory blocks 1 and 2 are read out through an address control similar to the writing. At the time of reading, data as shown in the figure J is outputted from the memory block 1, while data as shown in the figure K is outputted from the memory block 2. Output data of the memory blocks 1 and 2 are alternately selected by a selector 6, and accordingly the digital color video signal can be read out as shown in the figure L. Thus a clock system can be simplified, and a substrate can be scaled down, thereby facilitating the layout of the substrate.
