PURPOSE:To make it possible to make a memory element multifuntional by controlling the memory element, where various memories are incorporated, through gate circuits corresponding to switching of switches. CONSTITUTION:A memory element is constituted by different kinds of memory such as RAM1 and PROM2, and NOR gates 3a to 3c and 4a to 4c whose switching are controlled by the switching of switches 5a to 5c correspond to memories 1 and 2 respectively. Consequently, control signals which pass through gates 3a to 3a and 4a to 3c control memories 1 and 2 according to the switching of switches 5a to 5c, thereby making the memory element multi-functional. |
