An equalization circuit for a pair of resistive-capacitive data lines
includes primary and secondary equalization circuits attached at both
ends of the data line pair. A primary equalization circuit at one end of
the data line pair receives a primary control signal, and a secondary
equalization circuit at the other end of the data line pair receives a
secondary control signal, which is different than the primary control
signal. The equalization devices in the primary equalization circuit are
attached near the read and write amplifiers and operate normally since
all the information is available as to whether or not the corresponding
data line pair should be equalized. The additional equalization devices
in the secondary equalization circuit placed at the other end of the data
line pair receive a simpler control signal that lacks the information as
to whether or not any particular data line pair is being equalized.
