Abstract
PURPOSE: To shorten the information supply time as well as to realize the continuous supply of the information by giving the time-division serial conversion of the parallel reading information given from the plural units of memories alternately to two sets of high-speed memories which perform the reading alternately.
CONSTITUTION: The memory contents of high-speed RAM14a and 14b are read out alternately via control part 12 and then supplied to test circuit 16 and others via switch circuit 15. During this period, the information read out in parallel from RAM11a, 11b... are memorized in either one of memories 14a and 14b which is performing no reading via plural number of control part 12 after converted into the time-division serial data information by data multiplexer 13. Thus the supply time can be shortened for the continuous information through the alternate reading of the high-speed memory which memorizes the information read out in a short time by the parallel process.
