H5GQ2H24AFR

The flow diagram in Figure 7 illustrates the ABI operation. The controller decides whether to invert or not

invert the data conveyed on the address lines. The GDDR5 SGRAM has to perform the reverse operation

based on the level of the ABI# pin. Address input timing parameters are only valid with ABI being enabled

and a maximum of 4 address inputs driven Low.
