Conflict with two EEPROM

Hi,

With a STM32, I have a problem
to select either EEPROM (M24LR64-R and M24M02-DR) on the same bus I2C.

Here are the "device select code":

For M24LR64-R:  1 0 1 0     X 1  1 X

In the order:  1 0 1 0 = Device type identifier   X = E2   1 1 = E1 E0 ( chip enable)   X = RW


For M24M02-DR: 1 0 1 0   1 X X X

In the order: 1 0 1 0 = Device type identifier   1 = E2 ( chip enable)   X X = A17 A16 (MSB address bits )    X = RW


The two address bits A17 and A16 for M24M02-DR can not be used because they would pose a conflict with the R-M24LR64


there is there a way around the problem?

Thank you for your response,
