STACKED TYPE SEMICONDUCTOR MEMORY DEVICE AND CHIP SELECTION CIRCUIT |
摘要 |
A stacked type semiconductor memory device of having a structure in which a plurality of semiconductor chips is stacked and a desired semiconductor chip can be selected by assigning a plurality of chip identification numbers different from each other are individually assigned to the plurality of semiconductor chips comprising: a plurality of operation circuits which is connected in cascade in a stacking order of the plurality of semiconductor chips and outputs the plurality of identification numbers different from each other by performing a predetermined operation; and a plurality of comparison circuits which detects whether or not each the identification number and a chip selection address commonly connected to each the semiconductor chip are equal to each other by comparing them.
