PURPOSE:To facilitate a high degree of integration by a method wherein vertical multiple chip composition is applied to chip mounting. CONSTITUTION:A vertical multiple chip is composed of memories 1, 2, i.e., the memories 1, 2 are block constituents of the title memory integrated circuit and in case the chip select 3 is 'L', the memory 1 is to be selected, while in case the chip select 3 is 'H', the memory 2 is to be selected. Through these procedures, the circuit can be easily integrated to a high degree. |
