NOTE: **specification is only available on tolerant cells.
Driver Type A, B, C : Refer to DC currents table of output driver.
The specification is basically referred to JEDEC JESD8 standard and have extended interface voltage range of
1.7V~3.6V The specification can be changed depending on interface voltage
