(byte masking) rege register enable the device operates in the tr ansparent mode when rege is low. when rege is high, the device operates in the registered mode. in registered mode, the address and con- trol inputs are latched if clk is held at a hi gh or low logic level. the inputs are stored in the latch/flip-flop on the rising edge of clk. rege is tied to v dd through 10k ohm resistor on pcb. so if rege of module is floating, this module will be operated as reg- istered mode. dq0 ~ 63 data input/output data inputs/outputs are multiplexed on the same pins. cb0 ~ 7 check bit check bits for ecc. v dd /v ss power supply/ground power and ground for the input buffers and the core logic.
