Why does ISB and ISB1 show in the datasheet for asynchronous SRAM?

Latest Updated:03/16/2012

Question:

Why does the datasheet for asynchronous SRAM show two kinds of standby current, ISB and ISB1?

Answer:

The difference between ISB and ISB1 is input voltage level. ISB is the standby current of TTL input level, and ISB1 is that of MOS input level.
When the input voltage level is set to MOS level, standby current is lower than TTL input level.
