Timing of Vendor Code and Revision ID Generation on DQ[7:0]
4.2.6
Address command termination
The address and command termination is used to set the value of the internal termination resistors. The GDDR3 DRAM
supports ZQ / 4, ZQ / 2 and ZQ termination values. The mode register programming overwrites the programming during the
chip initialization.
4.2.7
Operation mode
The GDDR3 DRAM can be internally configured as two 512Mbit (2-CS mode) or one 1Gbit device (1-CS mode). The pins CS1
and A12 are only active in two, resp. 1-CS mode and act either as the chip select for the second rank, or the row-address for
the upper 4k-row-address range. If bit A2 from EMRS2 (“Merged Mode”) is set to 1 then the 2 operations mode will be inverted.
Note also that at 1000 MHz speed grade only 1-CS mode is supported.
