Translation - Japanese: アドレスピンには内部プルアップ、または 内部プルダウンはありますか? - Community Translated (JA)
Question: Do you have internal pullups or pulldowns on your address pins so that they may be left floating?
There are no pullups or pulldowns on address pins. If the customer doesn't want to use half of the memory, then any one of the address pins can be tied high or low and the remaining can be used to address the part.
