make a choice of memory power in SOC

[john7796]

Here has 2 memory device A and B:

The active current of A is 10 mA, B is 20 mA;

and leakage current of A is 20 uA, B is 10 uA.

For a hand on SOC design, like cellphone processor chip, which memory device is better choice? A or B?

Please help me.

If leakage is not an issue for the rest of the circuit, but power use is, A?
If power needed is ~20mA, and 10mA is not enough, B?

If leakage is not an issue for the rest of the circuit, but power use is, A?

If leakage is not an issue, should be B, B's leakage is smaller.

If power is an issue, should be A, A's active is smaller.

However I can't make sure the consideration of SOC design in cellphone processor chip.
