Abstract: There is described a network system for processing image data and printing an image based on the image data. The system includes image-processing apparatus and an image printing apparatus coupled to each other in a network. Each of the image-processing apparatus includes a rasterization processing section to generate first rasterized pixel data; an image data transmitting section to transmit the image data to another image-processing apparatus, which generates second rasterized pixel data; a pixel data receiving section to receive the second rasterized pixel data; and a pixel data transmitting section to transmit either the first rasterized pixel data or the second rasterized pixel data to the image printing apparatus as print-rasterized pixel data. The image printing apparatus includes a print-rasterized pixel data receiving section to receive the print-rasterized pixel data in order to print the image according to the print-rasterized pixel data.

Abstract: A pseudo static RAM includes an array of dynamic memory cells and peripheral circuits such as precharge transistors, a row decoder and sense amplifiers. Address change detecting circuits detect address signal change. A pulse generator supplies a pulse signal to a timing generator and a busy signal generator in response to the address signal change. The timing generator generates various timing signals for driving the peripheral circuits. When a subsequent address signal change is detected during operation of a dynamic RAM, a flag circuit generates a flag signal in response to a subsequent pulse signal from the pulse generator and a busy signal from the busy signal generator. Thus, the signal commanding such subsequent operation of the pseudo static RAM is stored in the form of a flag signal until the first operation is completed. Upon completion of first operation of the dynamic RAM, subsequent operation is started on the basis of the flag signal.
