Notes:
1. This configuration permits QWORD Write only.
2. Data and CLK are terminated using 10Ω series resistors.
3. REGE, when asserted active high the buffer-register operates
in “real-time” buffer mode, when deasserted inactive low the
buffer-register operates in Register mode.
4. Each 16Mx20 Block comprises of five 16Mx4 SDRAMs
and 16Mx16 Block comprises of four 16Mx4 SDRAMs.

Notes :
1. The unbuffered physical detect
pins IN and OUT are shorted
together on the DIMM.
2. Presence detect pins PD1~PD8 are
buffered and enabled by PDE#.
3. VDD and VDDQ are common for
this module.
4. A10/AP initiates auto precharge.
