    The relationship between Output High Voltage and Current of FRAM




      My customer is comparing the Voh level between FRAM and the host CPU.


      Voh_min of FRAM is Vdd - 0.8 = 2.5V (at Vdd = 3.3V).

      On the other hand, the Vih_min of the CPU is Vcc x 0.8 = 2.64V.


      There is a possibility that Voh of FRAM is lower than Vih of CPU.

      However, since the test condition of FRAM is as strict as 2 mA,

      so we think that it can be cleared by changing the conditions.


      Please provide information on the relationship between FRAM current value and Voh.


      Best Regards,
