Abstract

PURPOSE:To make access high-speed by detecting a page mode to not only supply successively only changed addresses but also shorten the clock period and the memory clock period in the address generator. CONSTITUTION:The row address signal at terminal 23R of pattern generator 21 is compared with a signal, which is obtained by delaying the row address signal by unit clock one period components in chain register 37, in comparator circuit 36. When circuit 36 outputs a non-coincidence signal, multiplexer 27 supplies row addresses and column addresses alternately to driver comparator 31. When circuit 36 outputs a coincidence signal, multiplexer 27 supplies only column addresses to driver comparator 31. Further, timing control circuit 42 is controlled by signals from terminal 41, thereby controlling the timing generation period of timing generator 33.
