Translation - Japanese: CMOS SRAMのフローティングデータ入力について - Community Translated (JA)
Question: I used a SRAM which has a x32 configuration and now I am forced to use a x36 configuration. I have the 4 unused inputs floating. Is this okay?
Answer:
It is not recommended to leave the CMOS inputs floating. None of the SRAM parts have any internal pullups or pulldowns on the data inputs to have a valid signal when an input is left floating. If the customer does not want to use the datalines for parity, they have to be pulled up or pulled down.
