Title: Memory device
Inventor: MURAMATSU HIROMI
IPC: G11C27/00
Filed: 1978-03-24
Abstract: PURPOSE: To obviate the change of storage voltage over a long time by using a counter as a memory element, DA-converting the output thereof and storing and holding the detection voltage of a desired timing.  
     CONSTITUTION: When a set signal SET is inputted, a counter 5 is cleared and the storage voltage Vo being the output of a DA converter 6 and the output of a differential amplifier 7 become "L" level. Since a flip-flop 8 is set by signal, a gate element 9 transmits the clock signal CK to the counter 5. When there is  no more set signal, the counter 5 counts the clock signal CK. As the storage voltage Vo rises and when this exceeds the detection voltage Vi, the output of the differential amplifier 7 becomes "H" level and resets the flip-flop 8. As a result, the reset state continues unitl the next set signal comes and the storage voltage Vo maintains a constant level and therefore the storage free from change with time may be accomplished.
