Abstract
A plurality of sequentially occuring information signals are stored in a memory by considering past record of the information signals. The number of times the same information occurs is counted, and when the information changes, the current count and the newly generated information are stored in the memory. The method of the invention thus enables much information to be stored in a small-capacity memory.
