Abstract

PURPOSE:To constitute a large-capacity memory unit which is capable of both the reading and writing of a large capacity independently through the simple-structure circuit and by means of the small capacity first-in/first-out memory and the comparatively large-capacity RAM. CONSTITUTION:The primary component parts are large-capacity RAM23 containing 1st and 2nd address counter 21 and 22 plus small-capacity first-in/first-out FIFO memory 24, and memory 23 and 24 can be connected via switch 25 in order to secure the mutual data shift. At the same time, input/output terminal 27 is connected to switch 25, and switch 27 is connected to counter 21 and 22. Thus, RAM23 and memory 24 can be controlled by writing and reading control pulse W and R. And when terminal 26 and 27 are used for the input and output terminals, the writing and reading action are carried out by RAM23 and memory 24 respectively. In case memory 24 is given the reading action and the input and the output are made opposite among terminal 26 and 27, the operations are made opposite between RAM23 and memory 24.
