REGE, when asserted active high the buffer-register operates in register mode,
when deasserted inactive low the buffer-register operates in “real-time” buffer mode.
Registers Block comprises of two registers.
Each 4Mx48 Block comprises of three 4Mx16 SDRAMs and
Data is terminated using 10
Ω
series resistors.
For RDQMB control see note on page 2.
CLK signals are terminated with series resistors and/or padding capacitors
depending on load per clock.
WP signal has a pull-up of 100K
